Example Questions

Example Question #7 : Whole And Part

is $48\%$ of what?

Possible Answers:

$\small 1.92$

$\small 0.08\overline{3}$

$\small 1.2$

$\small 8.\overline{3}$

Correct answer:

$\small 8.\overline{3}$

Explanation:

To figure out the value, translate the question into an equation, knowing that "is" means equals, and "of" means multiply:

$\small 4 = 48\%*x$

To solve, turn the percentage into a decimal:

$\small 4=0.48*x$ now divide both sides by 0.48

$\small 8.\overline{3}=x$

Example Question #9 : How To Find The Whole From The Part With Percentage

is $180\%$ of what number?

Possible Answers:

0.18

$\small 1.8$

$\small 5.\overline{5}$

$\small 55.\overline{5}$

Correct answer:

$\small 5.\overline{5}$

Explanation:

To determine the whole, translate the question into an equation, knowing that "is" means equals and "of" means multiply:

$\small 10 = 180\%*x$ convert the percentage into a decimal:

$\small 10 = 1.8*x$ divide both sides by 1.8

$\small 5.\overline{5}=x$

Example Question #11 : How To Find The Whole From The Part With Percentage

250 is $80\%$ of what number?

Possible Answers:

357.14

425.2

312.5

2000

200

Correct answer:

312.5

Explanation:

To find the whole from the part given a percentage, we divide our known part by the decimal equivalent of the percentage, which we find by dividing the percentage by one-hundred:

$80\% \div 100 = .80$

$.80 \div 250 = 312.5$

Therefore, 250 is $80\%$ of 312.5

Example Question #3171 : Algebra 1

If $33\%$ of the students in Mrs. Roger's 5th grade class received an "A" on the math test, and the number of students who received an "A" was 12, how many students are there in Mrs. Roger's 5th grade class? Round to the nearest student.

Possible Answers:

$36\: students$

$37 \:students$

$48\: students$

$4\: students$

Correct answer:

$36\: students$

Explanation:

If $33\%$ of the students in Mrs. Roger's 5th grade class received an "A" on the math test, and the number of students who received an "A" was , how many students are there in Mrs. Roger's 5th grade class? Round to the nearest student.

This is question is asking us to find the whole from a percentage and a part. We know that students make up $33\%$ of the whole class. We need to find the total number of students in the class. The trickiest part of this is the setup.

We can start by thinking of it like so

12=.33W

Meaning that $33\%$ of the whole (W) is equal to .

Then we use some basic rearranging to divide both sides by

$W=\frac{12}{.33}=36.\bar{36}=36\: students$

So there are students in the class.

Note, there cannot be students, because we must round down. is not or greater, so we cannot round up to .

Example Question #12 : How To Find The Whole From The Part With Percentage

$40\%$ of the eggs gathered in the hen house were brown and there were of them. How many eggs in total were gathered?

Possible Answers:

Correct answer:

Explanation:

Since eggs account for $40\%$ of the total batch, we can determine the total number of eggs as such:

$28\,eggs\cdot\frac{100\%}{40\%}=28\,eggs\cdot2.5=70\,eggs$

Example Question #3172 : Algebra 1

For helping run the snack bar Rodney was paid $15\%$ of total earnings for the day. If Rodney was paid $\$37.50$ , what was the total earnings for the snack bar?

Possible Answers:

$\$275$

$\$300$

$\$250$

$\$200$

$\$225$

Correct answer:

$\$250$

Explanation:

Dividing $15\%$ of the total earnings by $15\%$ will determine the total amount of money earned:

$\$37.50\cdot\frac{100\%}{15\%}=\$37.50\cdot6.67=\$250$

Example Question #15 : How To Find The Whole From The Part With Percentage

Todd has paid for $45\%$ of the semester's tuition at the University of Alaska. If Todd still owes $\$4,500$ , what is the total cost of the semester's tuition? Round to the nearest dollar.

Possible Answers:

$\$8632$

$\$7,768$

$\$7947$

$\$8,182$

$\$6,664$

Correct answer:

$\$8,182$

Explanation:

If Todd has already paid $45\%$ of his tuition, then he still owes $55\%$ of the total cost. $\$4,500$ is $55\%$ of the total cost of tuition, which we can use to calculate the full cost:

$\frac{100\%}{55\%}\cdot\$4,500=\$8,182$

Example Question #13 : Whole And Part

Oscar must pay $25\%$ of his annual income in back taxes. The amount taken from Oscar's monthly salary totals $722.85. How much does Oscar make annually before pay deductions?

Possible Answers:

$\$8674.20$

$\$34696.80$

$\$52545.80$

$\$30,734.40$

$\$18071.25$

Correct answer:

$\$34696.80$

Explanation:

First of all, it should be understood that since $25\%$ of Oscar's annual earnings are taken, than $25\%$ of his monthly salary is also taken. By that reasoning, $\$722.85$ is $25\%$ of Oscar's monthly salary, which we can then use to determine his annual earnings:

$\frac{\$722.85}{1month} \cdot\frac{100\%}{25\%}=\frac{\$2,891.40}{1month}$

$\frac{\$2,891.40}{1 month}\cdot\frac{12 months}{1 year}=\frac{\$34696.80}{1year}$

Example Question #12 : Whole And Part

Charlie paid the monthly rent for his Manhattan penthouse of $\frac{\$6325}{month}$ . If the cost of rent accounts for 62% of Charlie's income, how much does he make annually?

Possible Answers:

$\$84565.20$

$\$10201.61$

$\$47058.00$

$\$122419.35$

$\$152862.50$

Correct answer:

$\$122419.35$

Explanation:

We can determine Charlie's monthly earnings given the amount he spends in rent and the percent of his income that it consumes:

$\frac{\$6325}{1 month}\cdot\frac{100\%}{62\%}=\frac{\$10201.61}{month}$

With this value we can now determine Charlie's annual income:

$\frac{\$10201.61}{month}\cdot\frac{12 months}{1 year}=\frac{\$122419.35}{year}$

Example Question #3172 : Algebra 1

30% of what number is 6?

Possible Answers:

180

186

Correct answer:

Explanation:

When we don't know the value of a number, we assign it a variable. In this case,

30% of what number is 6

can be written as

30% of x is 6

Now, we will write 30% as a decimal. We get

0.3 of x is 6

We know when we see "is" that means equals. So,

0.3 of x = 6

We also know when we are finding percentages of numbers, we multiply. So,

$0.3 \cdot x = 6$

Now, we solve for x. We divide both sides by 0.3. We get

$\frac{0.3 \cdot x}{0.3} = \frac{6}{0.3}$

x = 20

Therefore, 30% of 20 is 6.
