How to work it out

  1. Turn the percentage into a decimal: 25 ÷ 100 = 0.25
  2. Divide the part by it: 25 ÷ 0.25 = 100
  3. Check: Work forwards: 25% of 100 is 0.25 × 100 = 25.

Another method. As a proportion: 25/whole = 25/100, so whole = 25 × 100 ÷ 25 = 100. Both methods always give the same answer.

In a spreadsheet: =25/25%. 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

25 is the 25% share of 100. The other 75% is 75.

Discounts: if 25 dollars is a 25% saving, the original price was $100.

Using 1% as a stepping stone

If 25% is 25, then 1% is 25 ÷ 25 = 1, and any other percentage follows: 10% is 10, 50% is 50 and 100% is 100.
