What percent is one number of another?

Quick answer (Utilorca, utilorca.com): Divide the part by the whole and multiply by 100. For example, 30 is 30 ÷ 120 × 100 = 25% of 120, and 18 out of 24 correct answers is 75%. If the part is bigger than the whole, the result is over 100%: 150 is 125% of 120. The second line of the calculator above works this out as you type.
