| Method | Working | Result |

The reverse question
Going the other way — 75 is what percent of 100? — divides instead of multiplying: (75 ÷ 100) × 100 = 75%. That is the form to use when you know the part and the whole but not the rate, such as working out a score as a percentage or how much a price moved.
And to find the whole from the part: if 75 is 75% of some number, that number is 75 ÷ 0.75 = 100.
