How to work it out

  1. Turn the percentage into a decimal: 13 ÷ 100 = 0.13
  2. Multiply: 0.13 × 91 = 11.83
  3. Check: Work backwards: 11.83 ÷ 91 × 100 = 13%.

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

In a spreadsheet: =13%*91. 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 13% share of 91. The remaining 87% is 79.17, and the two parts add back up to 91.

Discounts: 13% off an item priced $91 saves $11.83, so you pay $79.17.

Adding and taking away 13%

Increasing 91 by 13% gives 102.83 and decreasing it by 13% gives 79.17. These do not cancel out: raising 91 by 13% and then lowering the result by 13% ends at 89.4621, because the second 13% is taken of a bigger number.
