How to work it out

  1. Turn the percentage into a decimal: 42 ÷ 100 = 0.42
  2. Multiply: 0.42 × 27 = 11.34
  3. Check: Work backwards: 11.34 ÷ 27 × 100 = 42%.

Another method. As a proportion of part to whole: 42/100 = part/27, so part = 42 × 27 ÷ 100 = 11.34. Both methods always give the same answer.

In a spreadsheet: =42%*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

11.34 is the 42% share of 27. The remaining 58% is 15.66, and the two parts add back up to 27.

Discounts: 42% off an item priced $27 saves $11.34, so you pay $15.66.

Adding and taking away 42%

Increasing 27 by 42% gives 38.34 and decreasing it by 42% gives 15.66. These do not cancel out: raising 27 by 42% and then lowering the result by 42% ends at 22.2372, because the second 42% is taken of a bigger number.
