How to work it out

  1. Turn the percentage into a decimal: 5 ÷ 100 = 0.05
  2. Multiply: 0.05 × 87 = 4.35
  3. Check: Work backwards: 4.35 ÷ 87 × 100 = 5%.

Another method. As a proportion of part to whole: 5/100 = part/87, so part = 5 × 87 ÷ 100 = 4.35. Both methods always give the same answer.

In a spreadsheet: =5%*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

4.35 is the 5% share of 87. The remaining 95% is 82.65, and the two parts add back up to 87.

Discounts: 5% off an item priced $87 saves $4.35, so you pay $82.65.

Adding and taking away 5%

Increasing 87 by 5% gives 91.35 and decreasing it by 5% gives 82.65. These do not cancel out: raising 87 by 5% and then lowering the result by 5% ends at 86.7825, because the second 5% is taken of a bigger number.
