Find what percentage one number is of another
Divide the part by the whole and multiply by 100. For example, "30 is what percent of 200?" → 30 ÷ 200 × 100 = 15%. This reverse percentage calculation is useful for grades, statistics, budgeting, and comparing proportions.
If you scored 42 out of 50 on a test: 42 ÷ 50 × 100 = 84%. If 18 out of 120 employees work remotely: 18 ÷ 120 × 100 = 15%. If you spent $340 of your $2,000 budget: 340 ÷ 2000 × 100 = 17%.
