The reverse question
Going the other way — 100 is what percent of 250? — divides instead of multiplying: (100 ÷ 250) × 100 = 40%. 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 100 is 40% of some number, that number is 100 ÷ 0.4 = 250.
