Answer 1

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

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
