How to work it out

  1. Turn the percentage into a decimal: 10 ÷ 100 = 0.1
  2. Divide the part by it: 75 ÷ 0.1 = 750
  3. Check: Work forwards: 10% of 750 is 0.1 × 750 = 75.

Another method. As a proportion: 75/whole = 10/100, so whole = 75 × 100 ÷ 10 = 750. Both methods always give the same answer.

In a spreadsheet: =75/10%. 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 10% share of 750. The other 90% is 675.

Discounts: if 75 dollars is a 10% saving, the original price was $750.

Using 1% as a stepping stone

If 10% is 75, then 1% is 75 ÷ 10 = 7.5, and any other percentage follows: 10% is 75, 50% is 375 and 100% is 750.
