How to work it out

  1. Turn the percentage into a decimal: 87 ÷ 100 = 0.87
  2. Multiply: 0.87 × 89 = 77.43
  3. Check: Work backwards: 77.43 ÷ 89 × 100 = 87%.

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

In a spreadsheet: =87%*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

77.43 is the 87% share of 89. The remaining 13% is 11.57, and the two parts add back up to 89.

Discounts: 87% off an item priced $89 saves $77.43, so you pay $11.57.

Adding and taking away 87%

Increasing 89 by 87% gives 166.43 and decreasing it by 87% gives 11.57. These do not cancel out: raising 89 by 87% and then lowering the result by 87% ends at 21.6359, because the second 87% is taken of a bigger number.
