How to work it out

  1. Turn the percentage into a decimal: 50 ÷ 100 = 0.5
  2. Divide the part by it: 85 ÷ 0.5 = 170
  3. Check: Work forwards: 50% of 170 is 0.5 × 170 = 85.

Another method. As a proportion: 85/whole = 50/100, so whole = 85 × 100 ÷ 50 = 170. Both methods always give the same answer.

In a spreadsheet: =85/50%. 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

85 is the 50% share of 170. The other 50% is 85.

Discounts: if 85 dollars is a 50% saving, the original price was $170.

Using 1% as a stepping stone

If 50% is 85, then 1% is 85 ÷ 50 = 1.7, and any other percentage follows: 10% is 17, 50% is 85 and 100% is 170.
