X% of Y = (X ÷ 100) × Y • X as % of Y = (X ÷ Y) × 100 • % change = ((Y − X) ÷ X) × 100
How it works
- 1Percent means "per hundred": 25% is simply 25 out of every 100, or 0.25 as a decimal.
- 2To find a percentage of a number, divide the percentage by 100 and multiply.
- 3To express one number as a percentage of another, divide the part by the whole and multiply by 100.
