How to work it out

  1. Turn the percentage into a decimal: 50 ÷ 100 = 0.5
  2. Multiply: 0.5 × 54 = 27
  3. Check: Work backwards: 27 ÷ 54 × 100 = 50%.

Another method. As a proportion of part to whole: 50/100 = part/54, so part = 50 × 54 ÷ 100 = 27. Both methods always give the same answer.

In a spreadsheet: =50%*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

27 is the 50% share of 54. The remaining 50% is 27, and the two parts add back up to 54.

Discounts: 50% off an item priced $54 saves $27, so you pay $27.

Adding and taking away 50%

Increasing 54 by 50% gives 81 and decreasing it by 50% gives 27. These do not cancel out: raising 54 by 50% and then lowering the result by 50% ends at 40.5, because the second 50% is taken of a bigger number.
