How to work it out

  1. Turn the percentage into a decimal: 27 ÷ 100 = 0.27
  2. Multiply: 0.27 × 13 = 3.51
  3. Check: Work backwards: 3.51 ÷ 13 × 100 = 27%.

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

In a spreadsheet: =27%*13. 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 27% share of 13. The remaining 73% is 9.49, and the two parts add back up to 13.

Discounts: 27% off an item priced $13 saves $3.51, so you pay $9.49.

Adding and taking away 27%

Increasing 13 by 27% gives 16.51 and decreasing it by 27% gives 9.49. These do not cancel out: raising 13 by 27% and then lowering the result by 27% ends at 12.0523, because the second 27% is taken of a bigger number.
