How to work it out

  1. Turn the percentage into a decimal: 50 ÷ 100 = 0.5
  2. Divide the part by it: 55 ÷ 0.5 = 110
  3. Check: Work forwards: 50% of 110 is 0.5 × 110 = 55.

Another method. As a proportion: 55/whole = 50/100, so whole = 55 × 100 ÷ 50 = 110. Both methods always give the same answer.

In a spreadsheet: =55/50%. 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

55 is the 50% share of 110. The other 50% is 55.

Discounts: if 55 dollars is a 50% saving, the original price was $110.

Using 1% as a stepping stone

If 50% is 55, then 1% is 55 ÷ 50 = 1.1, and any other percentage follows: 10% is 11, 50% is 55 and 100% is 110.
