How to work it out
- Turn the percentage into a decimal: 25 ÷ 100 = 0.25
- Divide the part by it: 5 ÷ 0.25 = 20
- Check: Work forwards: 25% of 20 is 0.25 × 20 = 5.
Another method. As a proportion: 5/whole = 25/100, so whole = 5 × 100 ÷ 25 = 20. Both methods always give the same answer.
In a spreadsheet: =5/25%. 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
5 is the 25% share of 20. The other 75% is 15.
Discounts: if 5 dollars is a 25% saving, the original price was $20.
Using 1% as a stepping stone
If 25% is 5, then 1% is 5 ÷ 25 = 0.2, and any other percentage follows: 10% is 2, 50% is 10 and 100% is 20.
