How to work it out

  1. Turn the percentage into a decimal: 59 ÷ 100 = 0.59
  2. Multiply: 0.59 × 21 = 12.39
  3. Check: Work backwards: 12.39 ÷ 21 × 100 = 59%.

Another method. As a proportion of part to whole: 59/100 = part/21, so part = 59 × 21 ÷ 100 = 12.39. Both methods always give the same answer.

In a spreadsheet: =59%*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

12.39 is the 59% share of 21. The remaining 41% is 8.61, and the two parts add back up to 21.

Discounts: 59% off an item priced $21 saves $12.39, so you pay $8.61.

Adding and taking away 59%

Increasing 21 by 59% gives 33.39 and decreasing it by 59% gives 8.61. These do not cancel out: raising 21 by 59% and then lowering the result by 59% ends at 13.6899, because the second 59% is taken of a bigger number.
