How to work it out

  1. Turn the percentage into a decimal: 87 ÷ 100 = 0.87
  2. Multiply: 0.87 × 10 = 8.7
  3. Check: Work backwards: 8.7 ÷ 10 × 100 = 87%.

Another method. As a proportion of part to whole: 87/100 = part/10, so part = 87 × 10 ÷ 100 = 8.7. Both methods always give the same answer.

In a spreadsheet: =87%*10. 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

8.7 is the 87% share of 10. The remaining 13% is 1.3, and the two parts add back up to 10.

Discounts: 87% off an item priced $10 saves $8.7, so you pay $1.3.

Adding and taking away 87%

Increasing 10 by 87% gives 18.7 and decreasing it by 87% gives 1.3. These do not cancel out: raising 10 by 87% and then lowering the result by 87% ends at 2.431, because the second 87% is taken of a bigger number.
