How to work it out
- Turn the percentage into a decimal: 9 ÷ 100 = 0.09
- Multiply: 0.09 × 91 = 8.19
- Check: Work backwards: 8.19 ÷ 91 × 100 = 9%.
Another method. As a proportion of part to whole: 9/100 = part/91, so part = 9 × 91 ÷ 100 = 8.19. Both methods always give the same answer.
In a spreadsheet: =9%*91. 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
8.19 is the 9% share of 91. The remaining 91% is 82.81, and the two parts add back up to 91.

Adding and taking away 9%
Increasing 91 by 9% gives 99.19 and decreasing it by 9% gives 82.81. These do not cancel out: raising 91 by 9% and then lowering the result by 9% ends at 90.2629, because the second 9% is taken of a bigger number.
