How to work it out

  1. Turn the percentage into a decimal: 89 ÷ 100 = 0.89
  2. Multiply: 0.89 × 87 = 77.43
  3. Check: Work backwards: 77.43 ÷ 87 × 100 = 89%.

Another method. As a proportion of part to whole: 89/100 = part/87, so part = 89 × 87 ÷ 100 = 77.43. Both methods always give the same answer.

In a spreadsheet: =89%*87. 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

77.43 is the 89% share of 87. The remaining 11% is 9.57, and the two parts add back up to 87.

Discounts: 89% off an item priced $87 saves $77.43, so you pay $9.57.

Adding and taking away 89%

Increasing 87 by 89% gives 164.43 and decreasing it by 89% gives 9.57. These do not cancel out: raising 87 by 89% and then lowering the result by 89% ends at 18.0873, because the second 89% is taken of a bigger number.
