How to work it out

  1. Turn the percentage into a decimal: 21 ÷ 100 = 0.21
  2. Multiply: 0.21 × 22 = 4.62
  3. Check: Work backwards: 4.62 ÷ 22 × 100 = 21%.

Another method. As a proportion of part to whole: 21/100 = part/22, so part = 21 × 22 ÷ 100 = 4.62. Both methods always give the same answer.

In a spreadsheet: =21%*22. 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

4.62 is the 21% share of 22. The remaining 79% is 17.38, and the two parts add back up to 22.

Discounts: 21% off an item priced $22 saves $4.62, so you pay $17.38.

Adding and taking away 21%

Increasing 22 by 21% gives 26.62 and decreasing it by 21% gives 17.38. These do not cancel out: raising 22 by 21% and then lowering the result by 21% ends at 21.0298, because the second 21% is taken of a bigger number.
