How to work it out

  1. Turn the percentage into a decimal: 13 ÷ 100 = 0.13
  2. Multiply: 0.13 × 27 = 3.51
  3. Check: Work backwards: 3.51 ÷ 27 × 100 = 13%.

Another method. As a proportion of part to whole: 13/100 = part/27, so part = 13 × 27 ÷ 100 = 3.51. Both methods always give the same answer.

In a spreadsheet: =13%*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

3.51 is the 13% share of 27. The remaining 87% is 23.49, and the two parts add back up to 27.

Discounts: 13% off an item priced $27 saves $3.51, so you pay $23.49.

Adding and taking away 13%

Increasing 27 by 13% gives 30.51 and decreasing it by 13% gives 23.49. These do not cancel out: raising 27 by 13% and then lowering the result by 13% ends at 26.5437, because the second 13% is taken of a bigger number.
