How to work it out

  1. Turn the percentage into a decimal: 53 ÷ 100 = 0.53
  2. Multiply: 0.53 × 21 = 11.13
  3. Check: Work backwards: 11.13 ÷ 21 × 100 = 53%.

Another method. As a proportion of part to whole: 53/100 = part/21, so part = 53 × 21 ÷ 100 = 11.13. Both methods always give the same answer.

In a spreadsheet: =53%*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

11.13 is the 53% share of 21. The remaining 47% is 9.87, and the two parts add back up to 21.

Discounts: 53% off an item priced $21 saves $11.13, so you pay $9.87.

Adding and taking away 53%

Increasing 21 by 53% gives 32.13 and decreasing it by 53% gives 9.87. These do not cancel out: raising 21 by 53% and then lowering the result by 53% ends at 15.1011, because the second 53% is taken of a bigger number.
