How to work it out

  1. Turn the percentage into a decimal: 97 ÷ 100 = 0.97
  2. Multiply: 0.97 × 21 = 20.37
  3. Check: Work backwards: 20.37 ÷ 21 × 100 = 97%.

Another method. As a proportion of part to whole: 97/100 = part/21, so part = 97 × 21 ÷ 100 = 20.37. Both methods always give the same answer.

In a spreadsheet: =97%*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

20.37 is the 97% share of 21. The remaining 3% is 0.63, and the two parts add back up to 21.

Discounts: 97% off an item priced $21 saves $20.37, so you pay $0.63.

Adding and taking away 97%

Increasing 21 by 97% gives 41.37 and decreasing it by 97% gives 0.63. These do not cancel out: raising 21 by 97% and then lowering the result by 97% ends at 1.2411, because the second 97% is taken of a bigger number.
