How to work it out

  1. Turn the percentage into a decimal: 24 ÷ 100 = 0.24
  2. Multiply: 0.24 × 87 = 20.88
  3. Check: Work backwards: 20.88 ÷ 87 × 100 = 24%.

Another method. As a proportion of part to whole: 24/100 = part/87, so part = 24 × 87 ÷ 100 = 20.88. Both methods always give the same answer.

In a spreadsheet: =24%*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

20.88 is the 24% share of 87. The remaining 76% is 66.12, and the two parts add back up to 87.

Discounts: 24% off an item priced $87 saves $20.88, so you pay $66.12.

Adding and taking away 24%

Increasing 87 by 24% gives 107.88 and decreasing it by 24% gives 66.12. These do not cancel out: raising 87 by 24% and then lowering the result by 24% ends at 81.9888, because the second 24% is taken of a bigger number.
