How to work it out
- Turn the percentage into a decimal: 13 ÷ 100 = 0.13
- Multiply: 0.13 × 99 = 12.87
- Check: Work backwards: 12.87 ÷ 99 × 100 = 13%.
Another method. As a proportion of part to whole: 13/100 = part/99, so part = 13 × 99 ÷ 100 = 12.87. Both methods always give the same answer.
In a spreadsheet: =13%*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
12.87 is the 13% share of 99. The remaining 87% is 86.13, and the two parts add back up to 99.
Discounts: 13% off an item priced $99 saves $12.87, so you pay $86.13.
Adding and taking away 13%
Increasing 99 by 13% gives 111.87 and decreasing it by 13% gives 86.13. These do not cancel out: raising 99 by 13% and then lowering the result by 13% ends at 97.3269, because the second 13% is taken of a bigger number.
