How to work it out

  1. Turn the percentage into a decimal: 91 ÷ 100 = 0.91
  2. Multiply: 0.91 × 13 = 11.83
  3. Check: Work backwards: 11.83 ÷ 13 × 100 = 91%.

Another method. As a proportion of part to whole: 91/100 = part/13, so part = 91 × 13 ÷ 100 = 11.83. Both methods always give the same answer.

In a spreadsheet: =91%*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

11.83 is the 91% share of 13. The remaining 9% is 1.17, and the two parts add back up to 13.

Discounts: 91% off an item priced $13 saves $11.83, so you pay $1.17.

Adding and taking away 91%

Increasing 13 by 91% gives 24.83 and decreasing it by 91% gives 1.17. These do not cancel out: raising 13 by 91% and then lowering the result by 91% ends at 2.2347, because the second 91% is taken of a bigger number.
