How to work it out
- Turn the percentage into a decimal: 20 ÷ 100 = 0.2
- Divide the part by it: 5 ÷ 0.2 = 25
- Check: Work forwards: 20% of 25 is 0.2 × 25 = 5.
Another method. As a proportion: 5/whole = 20/100, so whole = 5 × 100 ÷ 20 = 25. Both methods always give the same answer.
In a spreadsheet: =5/20%. 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.
