Match the quantity 13 in each problem on the right to its part of the percent problem on the left. some options on the left
will be used more than once.
percent
62% of what number is 13?
base
13 is 105% of what number?
amount
what is 13% of 85?
what percent of 13 is 4?
72% of 13 is what number?

62% of what number is 13 ⇒ amount

13 is 105% of what number ⇒ amount

What is 13% of 85 ⇒ percent

What percent of 13 is 4 ⇒ base

72% of 13 is what number ⇒ base

Step-by-step explanation:

* Lets explain how to solve the problem

- In any percentage problem there are three quantities

# The percent

# The base

# the amount

- Ex: 5 is 20% of 25 ⇒ 5 = 20% × 25

# 5 is the amount

# 20 is the percent

# 25 is the base

* Lets solve the problem

∵ 62% of what number is 13

∴ 62% × ? = 13

∴ 13 is amount

* 62% of what number is 13 ⇒ amount

∵ 13 is 105% of what number

∴ 13 = 105% × ?

∴ 13 is amount

* 13 is 105% of what number ⇒ amount

∵ What is 13% of 85

∴ ? = 13% × 85

∴ 13 is percent

* What is 13% of 85 ⇒ percent

∵ What percent of 13 is 4

∴ ? % × 13 = 4

∴ 13 is base

* What percent of 13 is 4 ⇒ base

∵ 72% of 13 is what number

∴ 72% × 13 = ?

∴ 13 is base

* 72% of 13 is what number ⇒ base
