How to work it out

  1. Turn the percentage into a decimal: 57 ÷ 100 = 0.57
  2. Multiply: 0.57 × 27 = 15.39
  3. Check: Work backwards: 15.39 ÷ 27 × 100 = 57%.

Another method. As a proportion of part to whole: 57/100 = part/27, so part = 57 × 27 ÷ 100 = 15.39. Both methods always give the same answer.

In a spreadsheet: =57%*27. 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

15.39 is the 57% share of 27. The remaining 43% is 11.61, and the two parts add back up to 27.

Discounts: 57% off an item priced $27 saves $15.39, so you pay $11.61.

Adding and taking away 57%

Increasing 27 by 57% gives 42.39 and decreasing it by 57% gives 11.61. These do not cancel out: raising 27 by 57% and then lowering the result by 57% ends at 18.2277, because the second 57% is taken of a bigger number.
