Step-by-step workings
Why this works
To find 15% of 50, we first convert the percentage to a decimal. 15% means 15 out of every 100, so we divide 15 by 100 to get 0.15. We then multiply this decimal by 50 to find our answer of 7.5.
This works because a percentage is simply a fraction of 100. 15% is the same as the fraction 3/20 (three twentieths). Multiplying any number by 0.15 gives you exactly 15 parts out of every 100 of that number.
Result = (15 ÷ 100) × 50
Result = 0.15 × 50 = 7.5
How to check your answer
To verify that 7.5 is 15% of 50, divide the answer by 50 and multiply by 100:
(7.5 ÷ 50) × 100 = 15%
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.
