How to work it out

  1. Turn the percentage into a decimal: 8 ÷ 100 = 0.08
  2. Multiply: 0.08 × 91 = 7.28
  3. Check: Work backwards: 7.28 ÷ 91 × 100 = 8%.

Another method. As a proportion of part to whole: 8/100 = part/91, so part = 8 × 91 ÷ 100 = 7.28. Both methods always give the same answer.

In a spreadsheet: =8%*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

7.28 is the 8% share of 91. The remaining 92% is 83.72, and the two parts add back up to 91.

Discounts: 8% off an item priced $91 saves $7.28, so you pay $83.72.

Adding and taking away 8%

Increasing 91 by 8% gives 98.28 and decreasing it by 8% gives 83.72. These do not cancel out: raising 91 by 8% and then lowering the result by 8% ends at 90.4176, because the second 8% is taken of a bigger number.
