How to work it out

  1. Turn the percentage into a decimal: 89 ÷ 100 = 0.89
  2. Multiply: 0.89 × 13 = 11.57
  3. Check: Work backwards: 11.57 ÷ 13 × 100 = 89%.

Another method. As a proportion of part to whole: 89/100 = part/13, so part = 89 × 13 ÷ 100 = 11.57. Both methods always give the same answer.

In a spreadsheet: =89%*13. 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

11.57 is the 89% share of 13. The remaining 11% is 1.43, and the two parts add back up to 13.

Discounts: 89% off an item priced $13 saves $11.57, so you pay $1.43.

Adding and taking away 89%

Increasing 13 by 89% gives 24.57 and decreasing it by 89% gives 1.43. These do not cancel out: raising 13 by 89% and then lowering the result by 89% ends at 2.7027, because the second 89% is taken of a bigger number.
