How to work it out

  1. Turn the percentage into a decimal: 39 ÷ 100 = 0.39
  2. Multiply: 0.39 × 100 = 39
  3. Check: Work backwards: 39 ÷ 100 × 100 = 39%.

Another method. As a proportion of part to whole: 39/100 = part/100, so part = 39 × 100 ÷ 100 = 39. Both methods always give the same answer.

In a spreadsheet: =39%*100. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

What the result means

39 is the 39% share of 100. The remaining 61% is 61, and the two parts add back up to 100.

Discounts: 39% off an item priced $100 saves $39, so you pay $61.

Adding and taking away 39%

Increasing 100 by 39% gives 139 and decreasing it by 39% gives 61. These do not cancel out: raising 100 by 39% and then lowering the result by 39% ends at 84.79, because the second 39% is taken of a bigger number.
