Applying Percents Study Guide

What is a percent .

A percent is a way of expressing a number as a fraction of 100. The symbol "%" is used to denote a percent . For example, 25% means 25 out of 100.

Converting Between Percents , Decimals , and Fractions

To convert a percent to a decimal , divide the percent by 100. For example, 25% is equivalent to 0.25 as a decimal .

To convert a percent to a fraction , write the percent as a fraction with a denominator of 100 and simplify if possible. For example, 25% is equivalent to 25/100, which simplifies to 1/4.

To convert a decimal to a percent , multiply the decimal by 100. For example, 0.25 is equivalent to 25% as a percent .

To convert a decimal to a fraction , write the decimal as a fraction and simplify if possible. For example, 0.25 is equivalent to 25/100, which simplifies to 1/4.

Calculating Percentages

To calculate a percentage of a number, multiply the number by the decimal equivalent of the percentage. For example, to find 25% of 80, you would calculate 0.25 * 80 = 20.

Percent Increase and Decrease

To calculate a percent increase, first find the difference between the new and original values. Then, divide the difference by the original value and multiply by 100. For example, if the original value is 50 and the new value is 65, the percent increase is ((65-50)/50) * 100 = 30%.

To calculate a percent decrease, use the same process as for percent increase, but with the difference being the original value minus the new value.

Discounts and Markups

To calculate the sale price of an item after a discount, subtract the discount amount from the original price. For example, if an item is originally $80 and there is a 20% discount, the sale price would be $80 - (0.20 * $80) = $64.

To calculate the selling price of an item after a markup, add the markup amount to the original price. For example, if an item is originally $50 and there is a 25% markup, the selling price would be $50 + (0.25 * $50) = $62.50.

Word Problems

When solving percent word problems , it's important to carefully read the problem and identify the known values and the unknown value. Then, set up an equation and solve for the unknown value using the methods described above.

Practice Problems

• What is 30% as a decimal ?
• Convert 0.6 to a percent .
• Find 15% of 200.
• If the original price of a shirt is $40 and it is discounted by 20%, what is the sale price?
• If a computer is marked up by 35% to a selling price of $810, what was its original price?

Good luck with your study of applying percents !

Eureka Math Grade 7 Module 4 Lesson 3 Answer Key

Engage ny eureka math 7th grade module 4 lesson 3 answer key, eureka math grade 7 module 4 lesson 3 example answer key.

Quantity = Percent × Whole Let p represent the unknown percent. 54 = p(300) \(\frac{1}{300}\) (54) = \(\frac{1}{300}\) (300)p \(\frac{54}{300}\) = 1p \(\frac{18}{100}\) = p \(\frac{18}{100}\) = 0.18 = 18% Anna and Emily were able to produce 18% of the total bracelets over the weekend.

b. Anna produced 32 of the 54 bracelets produced by Emily and Anna over the weekend. Write the number of bracelets that Emily produced as a percent of those that Anna produced. Answer: Arithmetic Method: 32 → 100% 1 → \(\frac{100}{32}\)% 22 → 22 ∙ \(\frac{100}{32}\)% 22 → 100 ∙ \(\frac{22}{32}\)% 22 → 100 ∙ 0.6875% 22 → 68.75%

Algebraic Method: Quantity = Percent × Whole Let p represent the unknown percent. 22 = p(32) \(\frac{1}{32}\) (22) = \(\frac{1}{32}\) (32)p \(\frac{22}{32}\) = 1p 0.6875 = p 0.6875 = 68.75%

22 bracelets are 68.75% of the number of bracelets that Anna produced. Emily produced 22 bracelets; therefore, she produced 68.75% of the number of bracelets that Anna produced.

c. Write the number of bracelets that Anna produced as a percent of those that Emily produced. Answer: Arithmetic Method: 22 → 100% 1 → \(\frac{100}{22}\)% 32 → 32 ∙ \(\frac{100}{22}\)% 32 → 100 ∙ \(\frac{32}{22}\)% 32 → 100 ∙ \(\frac{16}{11}\)% 32 → \(\frac{1600}{11}\)% 32 → 145 \(\frac{5}{11}\)%

Algebraic Method: Quantity = Percent × Whole Let p represent the unknown percent. 32 = p(22) \(\frac{1}{22}\) (32) = \(\frac{1}{22}\) (22)p \(\frac{32}{22}\) = 1p \(\frac{16}{11}\) = p 1 \(\frac{5}{11}\) = p 1 \(\frac{5}{11}\) = 1 \(\frac{5}{11}\) × 100% = 145 \(\frac{5}{11}\)%

32 bracelets are 145 \(\frac{5}{11}\)% of the number of bracelets that Emily produced. Anna produced 32 bracelets over the weekend, so Anna produced 145 \(\frac{5}{11}\)% of the number of bracelets that Emily produced.

Eureka Math Grade 7 Module 4 Lesson 3 Exercise Answer Key

Exercise 2. There are 750 students in the seventh – grade class and 625 students in the eighth – grade class at Kent Middle School. a. What percent is the seventh – grade class of the eighth – grade class at Kent Middle School? The number of eighth graders is the whole amount. Let p represent the percent of seventh graders compared to eighth graders. Quantity = Percent × Whole Let p represent the unknown percent. 750 = p(625) 750(\(\frac{1}{625}\)) = p(625)(\(\frac{1}{625}\)) 1.2 = p 1.2 = 120% The number of seventh graders is 120% of the number of eighth graders. There are 20% more seventh graders than eighth graders. Alternate solution: There are 125 more seventh graders. 125 = p(625), p = 0.20. There are 20% more seventh graders than eighth graders.

b. The principal will have to increase the number of eighth – grade teachers next year if the seventh – grade enrollment exceeds 110% of the current eighth – grade enrollment. Will she need to increase the number of teachers? Explain your reasoning. Answer: The principal will have to increase the number of teachers next year. In part (a), we found out that the seventh grade enrollment was 120% of the number of eighth graders, which is greater than 110%.

Exercise 3. At Kent Middle School, there are 104 students in the band and 80 students in the choir. What percent of the number of students in the choir is the number of students in the band? Answer: The number of students in the choir is the whole. Quantity = Percent × Whole Let p represent the unknown percent. 104 = p(80) p = 1.3 1.3 = 130% The number of students in the band is 130% of the number of students in the choir.

Teacher may ask students what percent less than the cost of lunch is the cost of breakfast. The cost of breakfast is 66\(\frac{2}{3}\)% less than the cost of lunch.

Exercise 5. Describe a real – world situation that could be modeled using the equation 398.4 = 0.83(x). Describe how the elements of the equation correspond with the real – world quantities in your problem. Then, solve your problem. Answer: Word problems will vary. Sample problem: A new tablet is on sale for 83% of its original sale price. The tablet is currently priced at $398.40. What was the original price of the tablet?

0.83 = \(\frac{83}{100}\) = 83%, so 0.83 represents the percent that corresponds with the current price. The current price ($398.40) is part of the original price; therefore, it is represented by 398.4. The original price is represented by x and is the whole quantity in this problem. 398.4 = 0.83x \(\frac{1}{0.83}\) (398.4) = \(\frac{1}{0.83}\) (0.83)x \(\frac{398.4}{0.83}\) = 1x 480 = x The original price of the tablet was $480.00.

Question 2. This year, Benny is 12 years old, and his mom is 48 years old. a. What percent of his mom’s age is Benny’s age? Answer: Let p represent the percent of Benny’s age to his mom’s age. 12 = p(48) p = 0.25 = 25% Benny’s age is 25% of his mom’s age.

b. What percent of Benny’s age is his mom’s age? Answer: Let p represent the percent of his mom’s age to Benny’s age. 48 = p(12) p = 4 = 400% Benny’s mom’s age is 400% of Benny’s age.

c. In two years, what percent of his age will Benny’s mom’s age be at that time? Answer: In two years, Benny will be 14, and his mom will be 50. 14 → 100% 1 → (\(\frac{100}{14}\))% 50 → 50(\(\frac{100}{14}\)% 50 → 25(\(\frac{100}{7}\))% 50 → (\(\frac{2500}{7}\))% 50 → 357 \(\frac{1}{7}\)% His mom’s age will be 357 \(\frac{1}{7}\)% of Benny’s age at that time.

d. In 10 years, what percent will Benny’s mom’s age be of his age? Answer: In 10 years, Benny will be 22 years old, and his mom will be 58 years old. 22 → 100% 1 → \(\frac{100}{22}\)% 58 → 58(\(\frac{100}{22}\))% 58 → 29(\(\frac{100}{11}\))% 58 → \(\frac{2900}{11}\)% 58 → 263 \(\frac{7}{11}\)% In 10 years, Benny’s mom’s age will be 263 \(\frac{7}{11}\)% of Benny’s age at that time.

e. In how many years will Benny be 50% of his mom’s age? Answer: Benny will be 50% of his mom’s age when she is 200% of his age (or twice his age). Benny and his mom are always 36 years apart. When Benny is 36, his mom will be 72, and he will be 50% of her age. So, in 24 years, Benny will be 50% of his mom’s age.

d. As Benny and his mom get older, Benny thinks that the percent of difference between their ages will decrease as well. Do you agree or disagree? Explain your reasoning. Answer: Student responses will vary. Some students might argue that they are not getting closer since they are always 36 years apart. However, if you compare the percents, you can see that Benny‘s age is getting closer to 100% of his mom’s age, even though their ages are not getting any closer.

Question 3. This year, Benny is 12 years old. His brother Lenny’s age is 175% of Benny’s age. How old is Lenny? Answer: Let L represent Lenny’s age. Benny’s age is the whole. L = 1.75(12) L = 21 Lenny is 21 years old.

Question 4. When Benny’s sister Penny is 24, Benny’s age will be 125% of her age. a. How old will Benny be then? Answer: Let b represent Benny’s age when Penny is 24. b = 1.25(24) b = 30 When Penny is 24, Benny will be 30.

b. If Benny is 12 years old now, how old is Penny now? Explain your reasoning. Answer: Penny is 6 years younger than Benny. If Benny is 12 now, then Penny is 6.

Question 5. Benny’s age is currently 200% of his sister Jenny’s age. What percent of Benny’s age will Jenny’s age be in 4 years? If Benny is 200% of Jenny’s age, then he is twice her age, and she is half of his age. Half of 12 is 6. Jenny is currently 6 years old. In 4 years, Answer: Jenny will be 10 years old, and Benny will be 16 years old. Quantity = Percent × Whole. Let p represent the unknown percent. Benny’s age is the whole. 10 = p(16) p = \(\frac{10}{16}\) p = \(\frac{5}{8}\) p = 0.625 = 62.5% In 4 years, Jenny will be 62.5% of Benny’s age.

Question 6. At the animal shelter, there are 15 dogs, 12 cats, 3 snakes, and 5 parakeets. a. What percent of the number of cats is the number of dogs? Answer: \(\frac{15}{12}\) = 1.25. That is 125%. The number of dogs is 125% the number of cats.

b. What percent of the number of cats is the number of snakes? Answer: \(\frac{3}{12}\) = \(\frac{1}{4}\) = 0.25. There are 25% as many snakes as cats.

c. What percent less parakeets are there than dogs? Answer: \(\frac{5}{15}\) = \(\frac{1}{3}\). That is 33 \(\frac{1}{3}\)%. There are 66 \(\frac{2}{3}\)% less parakeets than dogs.

d. Which animal has 80% of the number of another animal? Answer: \(\frac{12}{15}\) = \(\frac{4}{5}\) = \(\frac{8}{10}\) = 0.80. The number of cats is 80% the number of dogs.

e. Which animal makes up approximately 14% of the animals in the shelter? Answer: Quantity = Percent × Whole. The total number of animals is the whole. q = 0.14(35) q = 4.9 The quantity closest to 4.9 is 5, the number of parakeets.

Question 7. Is 2 hours and 30 minutes more or less than 10% of a day? Explain your answer. Answer: 2 hr.30 min. → 2.5 hr.; 24 hours is a whole day and represents the whole quantity in this problem. 10% of 24 hours is 2.4 hours. 2.5 > 2.4, so 2 hours and 30 minutes is more than 10% of a day.

Question 8. A club’s membership increased from 25 to 30 members. a. Express the new membership as a percent of the old membership. Answer: The old membership is the whole. Quantity = Percent × Whole. Let p represent the unknown percent. 30 = p(25) p = 1.2 = 120% The new membership is 120% of the old membership.

b. Express the old membership as a percent of the new membership. Answer: The new membership is the whole. 30 → 100% 1 → \(\frac{100}{30}\)% 25 → 25 ∙ \(\frac{100}{30}\)% 25 → 5 ∙ 1\(\frac{100}{6}\)% 25 → \(\frac{500}{6}\)% = 83 \(\frac{1}{3}\)% The old membership is 83 \(\frac{1}{3}\)% of the new membership.

Question 9. The number of boys in a school is 120% the number of girls at the school. a. Find the number of boys if there are 320 girls. Answer: The number of girls is the whole. Quantity = Percent × Whole. Let b represent the unknown number of boys at the school. b = 1.2(320) b = 384 If there are 320 girls, then there are 384 boys at the school.

b. Find the number of girls if there are 360 boys. Answer: The number of girls is still the whole. Quantity = Percent × Whole. Let g represent the unknown number of girls at the school. 360 = 1.2(g) g = 300 If there are 360 boys at the school, then there are 300 girls.

Question 10. The price of a bicycle was increased from $300 to $450. a. What percent of the original price is the increased price? Answer: The original price is the whole. Quantity = Percent × Whole. Let p represent the unknown percent. 450 = p(300) p = 1.5 1.5 = \(\frac{150}{100}\) = 150% The increased price is 150% of the original price.

b. What percent of the increased price is the original price? Answer: The increased price, $450, is the whole. 450 → 100% 1 → \(\frac{100}{450}\)% 300 → 300(\(\frac{100}{450}\))% 300 → 2(\(\frac{100}{3}\))% 300 → \(\frac{200}{3}\)% 300 → 66 \(\frac{2}{3}\)% The original price is 66 \(\frac{2}{3}\)% of the increased price.

Question 11. The population of Appleton is 175% of the population of Cherryton. a. Find the population in Appleton if the population in Cherryton is 4,000 people. Answer: The population of Cherryton is the whole. Quantity = Percent × Whole. Let a represent the unknown population of Appleton. a = 1.75(4,000) a = 7,000 If the population of Cherryton is 4,000 people, then the population of Appleton is 7,000 people.

b. Find the population in Cherryton if the population in Appleton is 10,500 people. Answer: The population of Cherryton is still the whole. Quantity = Percent × Whole. Let c represent the unknown population of Cherryton. 10,500 = 1.75c c = 10,500÷1.75 c = 6,000 If the population of Appleton is 10,500 people, then the population of Cherryton is 6,000 people.

c. Locate all points on the graph that would represent classrooms in which the number of girls y is 100% of the number of boys x. Describe the pattern that these points make. Answer: The points lie on a line that includes the origin; therefore, it is a proportional relationship.

d. Which points represent the classrooms in which the number of girls as a percent of the number of boys is greater than 100%? Which points represent the classrooms in which the number of girls as a percent of the number of boys is less than 100%? Describe the locations of the points in relation to the points in part (c). Answer: All points where y > x are above the line and represent classrooms where the number of girls is greater than 100% of the number of boys. All points where y < x are below the line and represent classrooms where the number of girls is less than 100% of the boys.

e. Find three ordered pairs from your table representing classrooms where the number of girls is the same percent of the number of boys. Do these points represent a proportional relationship? Explain your reasoning. Answer: There are two sets of points that satisfy this question: {(3,6), (5,10), and (11,22)}: The points do represent a proportional relationship because there is a constant of proportionality k = \(\frac{y}{x}\) = 2. {(4,2), (10,5), and (14,7)}: The points do represent a proportional relationship because there is a constant of proportionality k = \(\frac{y}{x}\) = \(\frac{1}{2}\).

g. What is the constant of proportionality in your equation(s), and what does it tell us about the number of girls and the number of boys at each point on the graph that represents it? What does the constant of proportionality represent in the table in part (a)? Answer: In the equation y = 2x, the constant of proportionality is 2, and it tells us that the number of girls will be twice the number of boys, or 200% of the number of boys, as shown in the table in part (a). In the equation y = 1/2 x, the constant of proportionality is 1/2, and it tells us that the number of girls will be half the number of boys, or 50% of the number of boys, as shown in the table in part (a).

Question 2. Jenny’s mom is 36 years old. What percent of Jenny’s mother’s age is Jenny’s great – grandmother’s age? Answer: Quantity = Percent × Whole. Let p represent the unknown percent. Jenny’s mother’s age is the whole. 90 = p(36) 90 ∙ \(\frac{1}{36}\) = p(36) ∙ \(\frac{1}{36}\) 5 ∙ \(\frac{1}{2}\) = p(1) 2.5 = p 2.5 = 250% Jenny’s great grandmother’s age is 250% of Jenny’s mother’s age.

Test Grade Calculator

How to calculate test score, test grade calculator – how to use it, test grade calculator – advanced mode options.

This test grade calculator is a must if you're looking for a tool to help set a grading scale . Also known as test score calculator or teacher grader , this tool quickly finds the grade and percentage based on the number of points and wrong (or correct) answers. Moreover, you can change the default grading scale and set your own. Are you still wondering how to calculate test scores? Scroll down to find out – or simply experiment with this grading scale calculator.

If this test grade calculator is not the tool you're exactly looking for, check out our other grading calculators like the grade calculator .

Prefer watching rather than reading? We made a video for you! Check it out below:

To calculate the percentile test score, all you need to do is divide the earned points by the total points possible . In other words, you're simply finding the percentage of good answers:

percentage score = (#correct / #total) × 100

As #correct + #wrong = #total , we can write the equation also as:

percentage score = 100 × (#total - #wrong) / #total

Then, all you need to do is convert the percentage score into a letter grade . The default grading scale looks as in the table below:

If you don't like using the +/- grades, the scale may look like:

• An A is 90% to 100%;
• A B is 80% to 89%;
• A C is 70% to 79%;
• A D is 60% to 69%; and finally
• F is 59% and below – and it's not a passing grade

Above, you can find the standard grading system for US schools and universities. However, the grading may vary among schools, classes, and teachers. Always check beforehand which system is used in your case.

Sometimes the border of passing score is not 60%, but, e.g., 50 or 65%. What then? We've got you covered – you can change the ranges of each grade! Read more about it in the last section of this article: Advanced mode options .

🙋 You might also be interested in our semester grade calculator and the final grade calculator .

Our test score calculator is a straightforward and intuitive tool!

Enter the number of questions/points/problems in the student's work (test, quiz, exam – anything). Assume you've prepared the test with 18 questions.

Type in the number the student got wrong . Instead – if you prefer – you can enter the number of gained points. Let's say our exemplary student failed to answer three questions.

Here we go! Teacher grader tool shows the percentage and grade for that score. For our example, the student scored 83.33% on a test, which corresponds to a B grade.

Underneath you'll find a full grading scale table . So to check the score for the next students, you can type in the number of questions they've got wrong – or just use this neat table.

That was a basic version of the test grade calculator. But our teacher grader is a much more versatile and flexible tool!

You can choose more options to customize this test score calculator. Just hit the Advanced mode button below the tool, and two more options will appear:

Increment by box – Here, you can change the look of the table you get as a result. The default value is 1, meaning the student can get an integer number of points. But sometimes it's possible to get, e.g., half-points – then you can use this box to declare the increment between the next scores.

Percentage scale – In this set of boxes, you can change the grading scale from the default one. For example, assume that the test was challenging and you'd like to change the scale so that getting 50% is already a passing grade (usually, it's 60% or even 65%). Change the last box, Grade D- ≥ value, from default 60% to 50% to reach the goal. You can also change the other ranges if you want to.

And what if I don't need +/- grades ? Well, then just ignore the signs 😄

How do I calculate my test grade?

To calculate your test grade:

• Determine the total number of points available on the test.
• Add up the number of points you earned on the test.
• Divide the number of points you earned by the total number of points available.
• Multiply the result by 100 to get a percentage score.

That's it! If you want to make this easier, you can use Omni's test grade calculator.

Is 27 out of 40 a passing grade?

This depends mainly on the grading scale that your teacher is using. If a passing score is defined as 60% (or a D-), then 27 out of 40 would correspond to a 67.5% (or a D+), which would be a passing grade. However, depending on your teacher’s scale, the passing score could be higher or lower.

What grade is 7 wrong out of 40?

This is a B-, or 82.5% . To get this result:

Use the following percentage score formula: percentage score = 100 × (#total - #wrong) / #total

Here, #total represents the total possible points, and #wrong , the number of incorrect answers.

Substitute your values: percentage score = 100 × (40 - 7) / 40 percentage score = 82.5%

Convert this percentage into a letter grade. In the default grading scale, 82.5% corresponds to a B-. However, grading varies — make sure to clarify with teachers beforehand.

Is 75 out of 80 an A?

Yes , a score of 75 out of 80 is an A according to the default grading scale. This corresponds to a percentage score of 93.75%.
