To find X% of Y, multiply Y by X and divide by 100. For example, 15% of 200 = 200 × 15 / 100 = 30.
20% of 50 is 10. The formula is: 50 × 20 / 100 = 10.
Divide the part by the whole and multiply by 100. For example, 30 is what percent of 200? → (30 / 200) × 100 = 15%.
Yes. The formula works with any numbers including decimals. For example, 12.5% of 80 = 80 × 12.5 / 100 = 10.
