How to work it out

  1. Turn the percentage into a decimal: 18 ÷ 100 = 0.18
  2. Multiply: 0.18 × 27 = 4.86
  3. Check: Work backwards: 4.86 ÷ 27 × 100 = 18%.

Another method. As a proportion of part to whole: 18/100 = part/27, so part = 18 × 27 ÷ 100 = 4.86. Both methods always give the same answer.

In a spreadsheet: =18%*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

4.86 is the 18% share of 27. The remaining 82% is 22.14, and the two parts add back up to 27.

Discounts: 18% off an item priced $27 saves $4.86, so you pay $22.14.

Adding and taking away 18%

Increasing 27 by 18% gives 31.86 and decreasing it by 18% gives 22.14. These do not cancel out: raising 27 by 18% and then lowering the result by 18% ends at 26.1252, because the second 18% is taken of a bigger number.
