How to work it out
- Turn the percentage into a decimal: 81 ÷ 100 = 0.81
- Multiply: 0.81 × 11 = 8.91
- Check: Work backwards: 8.91 ÷ 11 × 100 = 81%.
Another method. As a proportion of part to whole: 81/100 = part/11, so part = 81 × 11 ÷ 100 = 8.91. Both methods always give the same answer.
In a spreadsheet: =81%*11. 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
8.91 is the 81% share of 11. The remaining 19% is 2.09, and the two parts add back up to 11.
Discounts: 81% off an item priced $11 saves $8.91, so you pay $2.09.
Adding and taking away 81%
Increasing 11 by 81% gives 19.91 and decreasing it by 81% gives 2.09. These do not cancel out: raising 11 by 81% and then lowering the result by 81% ends at 3.7829, because the second 81% is taken of a bigger number.
