How to work it out

  1. Turn the percentage into a decimal: 11 ÷ 100 = 0.11
  2. Multiply: 0.11 × 20 = 2.2
  3. Check: Work backwards: 2.2 ÷ 20 × 100 = 11%.

Another method. As a proportion of part to whole: 11/100 = part/20, so part = 11 × 20 ÷ 100 = 2.2. Both methods always give the same answer.

In a spreadsheet: =11%*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

2.2 is the 11% share of 20. The remaining 89% is 17.8, and the two parts add back up to 20.

Discounts: 11% off an item priced $20 saves $2.2, so you pay $17.8.

Adding and taking away 11%

Increasing 20 by 11% gives 22.2 and decreasing it by 11% gives 17.8. These do not cancel out: raising 20 by 11% and then lowering the result by 11% ends at 19.758, because the second 11% is taken of a bigger number.
