How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 72 = 22.32
  3. Check: Work backwards: 22.32 ÷ 72 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/72, so part = 31 × 72 ÷ 100 = 22.32. Both methods always give the same answer.

In a spreadsheet: =31%*72. 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

22.32 is the 31% share of 72. The remaining 69% is 49.68, and the two parts add back up to 72.

Discounts: 31% off an item priced $72 saves $22.32, so you pay $49.68.

Adding and taking away 31%

Increasing 72 by 31% gives 94.32 and decreasing it by 31% gives 49.68. These do not cancel out: raising 72 by 31% and then lowering the result by 31% ends at 65.0808, because the second 31% is taken of a bigger number.
