How to work it out

  1. Turn the percentage into a decimal: 87 ÷ 100 = 0.87
  2. Multiply: 0.87 × 28 = 24.36
  3. Check: Work backwards: 24.36 ÷ 28 × 100 = 87%.

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

In a spreadsheet: =87%*28. 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 87% share of 28. The remaining 13% is 3.64, and the two parts add back up to 28.

Discounts: 87% off an item priced $28 saves $24.36, so you pay $3.64.

Adding and taking away 87%

Increasing 28 by 87% gives 52.36 and decreasing it by 87% gives 3.64. These do not cancel out: raising 28 by 87% and then lowering the result by 87% ends at 6.8068, because the second 87% is taken of a bigger number.
