How to work it out

  1. Turn the percentage into a decimal: 22 ÷ 100 = 0.22
  2. Multiply: 0.22 × 21 = 4.62
  3. Check: Work backwards: 4.62 ÷ 21 × 100 = 22%.

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

In a spreadsheet: =22%*21. 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 22% share of 21. The remaining 78% is 16.38, and the two parts add back up to 21.

Discounts: 22% off an item priced $21 saves $4.62, so you pay $16.38.

Adding and taking away 22%

Increasing 21 by 22% gives 25.62 and decreasing it by 22% gives 16.38. These do not cancel out: raising 21 by 22% and then lowering the result by 22% ends at 19.9836, because the second 22% is taken of a bigger number.
