Question

16% of what number is 72?

Answer 1

We have, 16% = 72

or,

16/100

x = 72

Multiplying both sides by 100 and dividing both sides by 16,

we have x = 72 ×

100

16

x = 450

If you are using a calculator, simply enter 72×100÷16, which will give you the answer.

x=450

Answer 2

Answer: 450

Step-by-step explanation: Well we know that 16% means 16/100 since a percent just means over 100, of means times, what number means x, is, means equals, and 72 means 72.

So we have 16/100 · X = 72.

Notice that 16/100 can be reduced to 4/25.

So rewriting our problem we have 4x/25 = 72

To get rid of the fraction,

we multiply both sides of the equation by 25 and we have 4x = 1800.

Dividing both sides by 4, x = 450.
