Quick answer

How do you calculate a percentage?

To find what percentage one value is of a total, divide it by the total and multiply by 100: (value ÷ total) × 100. Example: 45 out of 180 gives (45 ÷ 180) × 100 = 25%. To work out X% of a number, multiply X by the number and divide by 100: 15% of 250 = 15 × 250 ÷ 100 = 37.5.
