How to work it out

  1. Turn the percentage into a decimal: 23 ÷ 100 = 0.23
  2. Multiply: 0.23 × 21 = 4.83
  3. Check: Work backwards: 4.83 ÷ 21 × 100 = 23%.

Another method. As a proportion of part to whole: 23/100 = part/21, so part = 23 × 21 ÷ 100 = 4.83. Both methods always give the same answer.

In a spreadsheet: =23%*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

4.83 is the 23% share of 21. The remaining 77% is 16.17, and the two parts add back up to 21.

Discounts: 23% off an item priced $21 saves $4.83, so you pay $16.17.

Adding and taking away 23%

Increasing 21 by 23% gives 25.83 and decreasing it by 23% gives 16.17. These do not cancel out: raising 21 by 23% and then lowering the result by 23% ends at 19.8891, because the second 23% is taken of a bigger number.
