| Method | Working | Result |

The reverse question
Going the other way — 30 is what percent of 150? — divides instead of multiplying: (30 ÷ 150) × 100 = 20%. 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 30 is 20% of some number, that number is 30 ÷ 0.2 = 150.
