How to work it out

  1. Turn the percentage into a decimal: 87 ÷ 100 = 0.87
  2. Multiply: 0.87 × 9 = 7.83
  3. Check: Work backwards: 7.83 ÷ 9 × 100 = 87%.

Another method. As a proportion of part to whole: 87/100 = part/9, so part = 87 × 9 ÷ 100 = 7.83. Both methods always give the same answer.

In a spreadsheet: =87%*9. 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

7.83 is the 87% share of 9. The remaining 13% is 1.17, and the two parts add back up to 9.

Discounts: 87% off an item priced $9 saves $7.83, so you pay $1.17.

Adding and taking away 87%

Increasing 9 by 87% gives 16.83 and decreasing it by 87% gives 1.17. These do not cancel out: raising 9 by 87% and then lowering the result by 87% ends at 2.1879, because the second 87% is taken of a bigger number.
