How it works

Percentages turn a fraction into a per-hundred figure, the everyday language of discounts, tips, interest, and statistics. This finds a percentage of a number and shows the result of adding or subtracting it.

Frequently asked questions

How do I find what percent one number is of another?

Divide the part by the whole and multiply by 100. For example, 45 out of 180 is 45 ÷ 180 × 100 = 25%.
