How to work it out
- Turn the percentage into a decimal: 87 ÷ 100 = 0.87
- Multiply: 0.87 × 99 = 86.13
- Check: Work backwards: 86.13 ÷ 99 × 100 = 87%.
Another method. As a proportion of part to whole: 87/100 = part/99, so part = 87 × 99 ÷ 100 = 86.13. Both methods always give the same answer.
In a spreadsheet: =87%*99. 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
86.13 is the 87% share of 99. The remaining 13% is 12.87, and the two parts add back up to 99.

Adding and taking away 87%
Increasing 99 by 87% gives 185.13 and decreasing it by 87% gives 12.87. These do not cancel out: raising 99 by 87% and then lowering the result by 87% ends at 24.0669, because the second 87% is taken of a bigger number.
