How to work it out
- Turn the percentage into a decimal: 75 ÷ 100 = 0.75
- Divide the part by it: 45 ÷ 0.75 = 60
- Check: Work forwards: 75% of 60 is 0.75 × 60 = 45.
Another method. As a proportion: 45/whole = 75/100, so whole = 45 × 100 ÷ 75 = 60. Both methods always give the same answer.
In a spreadsheet: =45/75%. 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
