Question

Identify the percent, amount and base in this problem: 3% of what number is 45?

Answer 1

Explanation:

3% of what number is 45......percent of base = amount

the percent is the number with the percent sign......so its 3%

the base is the number we are taking the percent of...so the base is unknown

the amount is the number that relates to the percent, it is a portion of the whole number...and it is 45

Answer 2

x = 1,500

Explanation:

We are given that

3% ⋅ x = 45

or 3/100 ⋅ x = 45

Multiply both sides by 100 and divide both sides by 3

x = 45 ⋅ 100/3

So:

x = 1,500

I hope this helps!

(Btw, if you're using a calculator you can just inter 45 ⋅ 100 ÷ 3, and that will give you the answer.)
