How to work it out

  1. Turn the percentage into a decimal: 71 ÷ 100 = 0.71
  2. Multiply: 0.71 × 21 = 14.91
  3. Check: Work backwards: 14.91 ÷ 21 × 100 = 71%.

Another method. As a proportion of part to whole: 71/100 = part/21, so part = 71 × 21 ÷ 100 = 14.91. Both methods always give the same answer.

In a spreadsheet: =71%*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

14.91 is the 71% share of 21. The remaining 29% is 6.09, and the two parts add back up to 21.

Discounts: 71% off an item priced $21 saves $14.91, so you pay $6.09.

Adding and taking away 71%

Increasing 21 by 71% gives 35.91 and decreasing it by 71% gives 6.09. These do not cancel out: raising 21 by 71% and then lowering the result by 71% ends at 10.4139, because the second 71% is taken of a bigger number.
