How do I calculate a percentage of a number?
Multiply the number by the percentage and divide by 100. 15% of 200 = 200 × 15 ÷ 100 = 30.
How do I work out a discount price?
Find the discount amount here (for example 25% of 400 = 100), then subtract it: 400 − 100 = 300. For a 25% discount you can also multiply by 0.75.
What percent is one number of another?
Divide the part by the whole and multiply by 100. 30 out of 200 = 30 ÷ 200 × 100 = 15%.
