How to work it out

  1. Turn the percentage into a decimal: 25 ÷ 100 = 0.25
  2. Divide the part by it: 75 ÷ 0.25 = 300
  3. Check: Work forwards: 25% of 300 is 0.25 × 300 = 75.

Another method. As a proportion: 75/whole = 25/100, so whole = 75 × 100 ÷ 25 = 300. Both methods always give the same answer.

In a spreadsheet: =75/25%. 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

75 is the 25% share of 300. The other 75% is 225.

Discounts: if 75 dollars is a 25% saving, the original price was $300.

Using 1% as a stepping stone

If 25% is 75, then 1% is 75 ÷ 25 = 3, and any other percentage follows: 10% is 30, 50% is 150 and 100% is 300.
