How to work it out
- Turn the percentage into a decimal: 91 ÷ 100 = 0.91
- Multiply: 0.91 × 9 = 8.19
- Check: Work backwards: 8.19 ÷ 9 × 100 = 91%.
Another method. As a proportion of part to whole: 91/100 = part/9, so part = 91 × 9 ÷ 100 = 8.19. Both methods always give the same answer.
In a spreadsheet: =91%*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
8.19 is the 91% share of 9. The remaining 9% is 0.81, and the two parts add back up to 9.
Discounts: 91% off an item priced $9 saves $8.19, so you pay $0.81.
Adding and taking away 91%
Increasing 9 by 91% gives 17.19 and decreasing it by 91% gives 0.81. These do not cancel out: raising 9 by 91% and then lowering the result by 91% ends at 1.5471, because the second 91% is taken of a bigger number.
