Step-by-step workings
Why this works
To find 5% of 300, we first convert the percentage to a decimal. 5% means 5 out of every 100, so we divide 5 by 100 to get 0.05. We then multiply this decimal by 300 to find our answer of 15.
This works because a percentage is simply a fraction of 100. 5% is the same as the fraction 1/20 (one twentieth). Multiplying any number by 0.05 gives you exactly 5 parts out of every 100 of that number.
Result = (5 ÷ 100) × 300
Result = 0.05 × 300 = 15
How to check your answer
To verify that 15 is 5% of 300, divide the answer by 300 and multiply by 100:
(15 ÷ 300) × 100 = 5%
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.
