How to work it out

  1. Turn the percentage into a decimal: 30 ÷ 100 = 0.3
  2. Multiply: 0.3 × 54 = 16.2
  3. Check: Work backwards: 16.2 ÷ 54 × 100 = 30%.

Another method. As a proportion of part to whole: 30/100 = part/54, so part = 30 × 54 ÷ 100 = 16.2. Both methods always give the same answer.

In a spreadsheet: =30%*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

16.2 is the 30% share of 54. The remaining 70% is 37.8, and the two parts add back up to 54.

Discounts: 30% off an item priced $54 saves $16.2, so you pay $37.8.

Adding and taking away 30%

Increasing 54 by 30% gives 70.2 and decreasing it by 30% gives 37.8. These do not cancel out: raising 54 by 30% and then lowering the result by 30% ends at 49.14, because the second 30% is taken of a bigger number.
