Step-by-step workings
Why this works
To find 20% of 50, we first convert the percentage to a decimal. 20% means 20 out of every 100, so we divide 20 by 100 to get 0.2. We then multiply this decimal by 50 to find our answer of 10.
This works because a percentage is simply a fraction of 100. 20% is the same as the fraction 1/5 (one fifth). Multiplying any number by 0.2 gives you exactly 20 parts out of every 100 of that number.
Result = (20 ÷ 100) × 50
Result = 0.2 × 50 = 10
How to check your answer
To verify that 10 is 20% of 50, divide the answer by 50 and multiply by 100:
(10 ÷ 50) × 100 = 20%
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.
