How to work it out

  1. Turn the percentage into a decimal: 1 ÷ 100 = 0.01
  2. Multiply: 0.01 × 87 = 0.87
  3. Check: Work backwards: 0.87 ÷ 87 × 100 = 1%.

Another method. As a proportion of part to whole: 1/100 = part/87, so part = 1 × 87 ÷ 100 = 0.87. Both methods always give the same answer.

In a spreadsheet: =1%*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

0.87 is the 1% share of 87. The remaining 99% is 86.13, and the two parts add back up to 87.

Discounts: 1% off an item priced $87 saves $0.87, so you pay $86.13.

Adding and taking away 1%

Increasing 87 by 1% gives 87.87 and decreasing it by 1% gives 86.13. These do not cancel out: raising 87 by 1% and then lowering the result by 1% ends at 86.9913, because the second 1% is taken of a bigger number.
