How to work it out

  1. Turn the percentage into a decimal: 18 ÷ 100 = 0.18
  2. Multiply: 0.18 × 43 = 7.74
  3. Check: Work backwards: 7.74 ÷ 43 × 100 = 18%.

Another method. As a proportion of part to whole: 18/100 = part/43, so part = 18 × 43 ÷ 100 = 7.74. Both methods always give the same answer.

In a spreadsheet: =18%*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

7.74 is the 18% share of 43. The remaining 82% is 35.26, and the two parts add back up to 43.

Discounts: 18% off an item priced $43 saves $7.74, so you pay $35.26.

Adding and taking away 18%

Increasing 43 by 18% gives 50.74 and decreasing it by 18% gives 35.26. These do not cancel out: raising 43 by 18% and then lowering the result by 18% ends at 41.6068, because the second 18% is taken of a bigger number.
