Question

What percent is... 50% of 50% of x?

Answer 1

The answer is 25
50% × 50 = (50/100) × 50 = 25

Answer 2

Convert both percents into decimals. To do that, move the percent sign two places to the left then multiply.

50% => 0.50
0.50 * 0.50 * x ; Start
0.25 * x            ; 0.50 * 0.50 is 0.25

The final answer is 0.25 * x. Which can also be expressed as 1/4x.
