How to work it out

  1. Turn the percentage into a decimal: 10 ÷ 100 = 0.1
  2. Multiply: 0.1 × 54 = 5.4
  3. Check: Work backwards: 5.4 ÷ 54 × 100 = 10%.

Another method. As a proportion of part to whole: 10/100 = part/54, so part = 10 × 54 ÷ 100 = 5.4. Both methods always give the same answer.

In a spreadsheet: =10%*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

5.4 is the 10% share of 54. The remaining 90% is 48.6, and the two parts add back up to 54.

Discounts: 10% off an item priced $54 saves $5.4, so you pay $48.6.

Adding and taking away 10%

Increasing 54 by 10% gives 59.4 and decreasing it by 10% gives 48.6. These do not cancel out: raising 54 by 10% and then lowering the result by 10% ends at 53.46, because the second 10% is taken of a bigger number.
