How to work it out

  1. Turn the percentage into a decimal: 3 ÷ 100 = 0.03
  2. Multiply: 0.03 × 87 = 2.61
  3. Check: Work backwards: 2.61 ÷ 87 × 100 = 3%.

Another method. As a proportion of part to whole: 3/100 = part/87, so part = 3 × 87 ÷ 100 = 2.61. Both methods always give the same answer.

In a spreadsheet: =3%*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

2.61 is the 3% share of 87. The remaining 97% is 84.39, and the two parts add back up to 87.

Discounts: 3% off an item priced $87 saves $2.61, so you pay $84.39.

Adding and taking away 3%

Increasing 87 by 3% gives 89.61 and decreasing it by 3% gives 84.39. These do not cancel out: raising 87 by 3% and then lowering the result by 3% ends at 86.9217, because the second 3% is taken of a bigger number.
