How to work it out

  1. Turn the percentage into a decimal: 89 ÷ 100 = 0.89
  2. Multiply: 0.89 × 31 = 27.59
  3. Check: Work backwards: 27.59 ÷ 31 × 100 = 89%.

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

In a spreadsheet: =89%*31. 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 89% share of 31. The remaining 11% is 3.41, and the two parts add back up to 31.

Discounts: 89% off an item priced $31 saves $27.59, so you pay $3.41.

Adding and taking away 89%

Increasing 31 by 89% gives 58.59 and decreasing it by 89% gives 3.41. These do not cancel out: raising 31 by 89% and then lowering the result by 89% ends at 6.4449, because the second 89% is taken of a bigger number.
