How to work it out

  1. Turn the percentage into a decimal: 18 ÷ 100 = 0.18
  2. Multiply: 0.18 × 54 = 9.72
  3. Check: Work backwards: 9.72 ÷ 54 × 100 = 18%.

Another method. As a proportion of part to whole: 18/100 = part/54, so part = 18 × 54 ÷ 100 = 9.72. Both methods always give the same answer.

In a spreadsheet: =18%*54. 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

9.72 is the 18% share of 54. The remaining 82% is 44.28, and the two parts add back up to 54.

Discounts: 18% off an item priced $54 saves $9.72, so you pay $44.28.

Adding and taking away 18%

Increasing 54 by 18% gives 63.72 and decreasing it by 18% gives 44.28. These do not cancel out: raising 54 by 18% and then lowering the result by 18% ends at 52.2504, because the second 18% is taken of a bigger number.
