How to work it out

  1. Turn the percentage into a decimal: 61 ÷ 100 = 0.61
  2. Multiply: 0.61 × 21 = 12.81
  3. Check: Work backwards: 12.81 ÷ 21 × 100 = 61%.

Another method. As a proportion of part to whole: 61/100 = part/21, so part = 61 × 21 ÷ 100 = 12.81. Both methods always give the same answer.

In a spreadsheet: =61%*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

12.81 is the 61% share of 21. The remaining 39% is 8.19, and the two parts add back up to 21.

Discounts: 61% off an item priced $21 saves $12.81, so you pay $8.19.

Adding and taking away 61%

Increasing 21 by 61% gives 33.81 and decreasing it by 61% gives 8.19. These do not cancel out: raising 21 by 61% and then lowering the result by 61% ends at 13.1859, because the second 61% is taken of a bigger number.
