Step-by-step workings
Why this works
To find 75% of 20, we first convert the percentage to a decimal. 75% means 75 out of every 100, so we divide 75 by 100 to get 0.75. We then multiply this decimal by 20 to find our answer of 15.
This works because a percentage is simply a fraction of 100. 75% is the same as the fraction 3/4 (three quarters). Multiplying any number by 0.75 gives you exactly 75 parts out of every 100 of that number.
Result = (75 ÷ 100) × 20
Result = 0.75 × 20 = 15
How to check your answer
To verify that 15 is 75% of 20, divide the answer by 20 and multiply by 100:
(15 ÷ 20) × 100 = 75%
This confirms the answer is correct. Dividing the part by the whole and multiplying by 100 is the standard way to find what percentage one number is of another.
