How to work it out

  1. Turn the percentage into a decimal: 21 ÷ 100 = 0.21
  2. Multiply: 0.21 × 43 = 9.03
  3. Check: Work backwards: 9.03 ÷ 43 × 100 = 21%.

Another method. As a proportion of part to whole: 21/100 = part/43, so part = 21 × 43 ÷ 100 = 9.03. Both methods always give the same answer.

In a spreadsheet: =21%*43. 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

9.03 is the 21% share of 43. The remaining 79% is 33.97, and the two parts add back up to 43.

Discounts: 21% off an item priced $43 saves $9.03, so you pay $33.97.

Adding and taking away 21%

Increasing 43 by 21% gives 52.03 and decreasing it by 21% gives 33.97. These do not cancel out: raising 43 by 21% and then lowering the result by 21% ends at 41.1037, because the second 21% is taken of a bigger number.
