How to work it out

  1. Turn the percentage into a decimal: 91 ÷ 100 = 0.91
  2. Multiply: 0.91 × 20 = 18.2
  3. Check: Work backwards: 18.2 ÷ 20 × 100 = 91%.

Another method. As a proportion of part to whole: 91/100 = part/20, so part = 91 × 20 ÷ 100 = 18.2. Both methods always give the same answer.

In a spreadsheet: =91%*20. 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

18.2 is the 91% share of 20. The remaining 9% is 1.8, and the two parts add back up to 20.

Discounts: 91% off an item priced $20 saves $18.2, so you pay $1.8.

Adding and taking away 91%

Increasing 20 by 91% gives 38.2 and decreasing it by 91% gives 1.8. These do not cancel out: raising 20 by 91% and then lowering the result by 91% ends at 3.438, because the second 91% is taken of a bigger number.
