The reverse question
Going the other way — 20 is what percent of 200? — divides instead of multiplying: (20 ÷ 200) × 100 = 10%. 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 20 is 10% of some number, that number is 20 ÷ 0.1 = 200.
