How to work it out
- Turn the percentage into a decimal: 30 ÷ 100 = 0.3
- Divide the part by it: 75 ÷ 0.3 = 250
- Check: Work forwards: 30% of 250 is 0.3 × 250 = 75.
Another method. As a proportion: 75/whole = 30/100, so whole = 75 × 100 ÷ 30 = 250. Both methods always give the same answer.
In a spreadsheet: =75/30%. Multiplying the part by the percentage instead of dividing gives a smaller number. The whole must be bigger than the part whenever the percentage is below 100.
What the result means
