How to work it out

  1. Turn the percentage into a decimal: 24 ÷ 100 = 0.24
  2. Multiply: 0.24 × 21 = 5.04
  3. Check: Work backwards: 5.04 ÷ 21 × 100 = 24%.

Another method. As a proportion of part to whole: 24/100 = part/21, so part = 24 × 21 ÷ 100 = 5.04. Both methods always give the same answer.

In a spreadsheet: =24%*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

5.04 is the 24% share of 21. The remaining 76% is 15.96, and the two parts add back up to 21.

Discounts: 24% off an item priced $21 saves $5.04, so you pay $15.96.

Adding and taking away 24%

Increasing 21 by 24% gives 26.04 and decreasing it by 24% gives 15.96. These do not cancel out: raising 21 by 24% and then lowering the result by 24% ends at 19.7904, because the second 24% is taken of a bigger number.
