Example Question #1 : How To Find The Whole From The Part
Find the whole from the part. Round to the nearest tenths place.
16 is 55% of what number?
To find the whole from a part, divide the "part" by the percent. But first, change the percent into a decimal (55% = 0.55)
Round to the nearest tenths place = 29.1.
Example Question #1 : How To Find The Whole From The Part
Roman is ordering uniforms for the tennis team. He knows how many people are on the team and how many uniforms come in each box. Which equation can be used to solve for how many boxes 
b = number of students ÷ number of uniforms per box
b = number of students - number of uniforms per box
b = number of students x number of uniforms per box
b = number of boxes ÷ number of uniforms per box
b = number of boxes x number of uniforms per box
b = number of students ÷ number of uniforms per box
The total number of uniforms needed equals the number of students divided by the number of uniforms per box.
Example Question #1 : How To Find The Whole From The Part
52 is 25% of what number?
208
13
1,300
240
208
To find the whole from the part, divide the “part” by the percent. In order to do this, first change the percent into a decimal (25% becomes 0.25).
Therefore, 52 is 25% of 208.

Example Question #1 : Whole And Part
Which of the following numbers is a multiple of ten?
A multiple is a number that can be divided by another number without a remainder. 30 can be divided by 10 without a remainder.
It is the only number from the list of answer choices for which this is true. Therefore, it is the correct answer.
Example Question #2 : Whole And Part
Andrea and her three friends all pitched in to buy a puppy. Each person paid equal parts. If Andrea paid 20 dollars, what was the total cost of the puppy?
We can solve this question with multiplication.
First, we know that Andrea paid 20 dollars and that each person paid equal parts. That means that each person paid 20 dollars.
Second, we know that there are four people total: Andrea and three additional friends.
Multiply the cost per person by the number of people to get the total cost.
Example Question #4 : How To Find The Whole From The Part
Together, Patricia, Alex and Steve compose 25 percent of their math club. How big is the math club?
10 people
9 people
4 people
12 people
12 people
If 3 people compose 25% of the math club, then 100% of the math club would consist of 4 times the number 3. This gives us a product of 12. Therefore, the correct answer is 12 people.
Example Question #6 : How To Find The Whole From The Part
Bessy is making shirts for her daughters. If 2 square feet of fabric is enough for her to make 1 shirt, how many shirts can she make with 9 square feet of fabric?
7 shirts
6 shirts
9 shirts
4 shirts
5 shirts
4 shirts
Given that 2 square feet of fabric is enough for Bessy to make 1 shirt, 9 square feet of fabric is 4.5 times the amount needed to make a shirt. This means that Bessy could make 4.5 shirts. Because making 0.5 shirts does not count as a full shirt, the correct answer is therefore 4 shirts.
