How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 89 = 27.59
  3. Check: Work backwards: 27.59 ÷ 89 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/89, so part = 31 × 89 ÷ 100 = 27.59. Both methods always give the same answer.

In a spreadsheet: =31%*89. 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

27.59 is the 31% share of 89. The remaining 69% is 61.41, and the two parts add back up to 89.

Discounts: 31% off an item priced $89 saves $27.59, so you pay $61.41.

Adding and taking away 31%

Increasing 89 by 31% gives 116.59 and decreasing it by 31% gives 61.41. These do not cancel out: raising 89 by 31% and then lowering the result by 31% ends at 80.4471, because the second 31% is taken of a bigger number.
