How to work it out

  1. Turn the percentage into a decimal: 11 ÷ 100 = 0.11
  2. Multiply: 0.11 × 99 = 10.89
  3. Check: Work backwards: 10.89 ÷ 99 × 100 = 11%.

Another method. As a proportion of part to whole: 11/100 = part/99, so part = 11 × 99 ÷ 100 = 10.89. Both methods always give the same answer.

In a spreadsheet: =11%*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

10.89 is the 11% share of 99. The remaining 89% is 88.11, and the two parts add back up to 99.

Discounts: 11% off an item priced $99 saves $10.89, so you pay $88.11.

Adding and taking away 11%

Increasing 99 by 11% gives 109.89 and decreasing it by 11% gives 88.11. These do not cancel out: raising 99 by 11% and then lowering the result by 11% ends at 97.8021, because the second 11% is taken of a bigger number.
