X is what % of Y questions
How do I work out what percentage one number is of another?
Divide the part by the total, then multiply by 100. 30 out of 150 = (30 ÷ 150) × 100 = 20%.
Which number goes on top?
The smaller part goes on top, the total on the bottom. Swapping them is the single most common mistake — 30 of 150 is 20%, but 150 of 30 is 500%.
What if the part is bigger than the total?
You get a result above 100%, which is valid. Selling 120 units against a target of 100 is 120% of target.
