How to work it out

  1. Turn the percentage into a decimal: 28 ÷ 100 = 0.28
  2. Multiply: 0.28 × 87 = 24.36
  3. Check: Work backwards: 24.36 ÷ 87 × 100 = 28%.

Another method. As a proportion of part to whole: 28/100 = part/87, so part = 28 × 87 ÷ 100 = 24.36. Both methods always give the same answer.

In a spreadsheet: =28%*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

24.36 is the 28% share of 87. The remaining 72% is 62.64, and the two parts add back up to 87.

Discounts: 28% off an item priced $87 saves $24.36, so you pay $62.64.

Adding and taking away 28%

Increasing 87 by 28% gives 111.36 and decreasing it by 28% gives 62.64. These do not cancel out: raising 87 by 28% and then lowering the result by 28% ends at 80.1792, because the second 28% is taken of a bigger number.
