How to work it out
- Turn the percentage into a decimal: 13 ÷ 100 = 0.13
- Multiply: 0.13 × 87 = 11.31
- Check: Work backwards: 11.31 ÷ 87 × 100 = 13%.
Another method. As a proportion of part to whole: 13/100 = part/87, so part = 13 × 87 ÷ 100 = 11.31. Both methods always give the same answer.
In a spreadsheet: =13%*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
11.31 is the 13% share of 87. The remaining 87% is 75.69, and the two parts add back up to 87.

Adding and taking away 13%
Increasing 87 by 13% gives 98.31 and decreasing it by 13% gives 75.69. These do not cancel out: raising 87 by 13% and then lowering the result by 13% ends at 85.5297, because the second 13% is taken of a bigger number.
