How to work it out

  1. Turn the percentage into a decimal: 11 ÷ 100 = 0.11
  2. Multiply: 0.11 × 13 = 1.43
  3. Check: Work backwards: 1.43 ÷ 13 × 100 = 11%.

Another method. As a proportion of part to whole: 11/100 = part/13, so part = 11 × 13 ÷ 100 = 1.43. Both methods always give the same answer.

In a spreadsheet: =11%*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

1.43 is the 11% share of 13. The remaining 89% is 11.57, and the two parts add back up to 13.

Discounts: 11% off an item priced $13 saves $1.43, so you pay $11.57.

Adding and taking away 11%

Increasing 13 by 11% gives 14.43 and decreasing it by 11% gives 11.57. These do not cancel out: raising 13 by 11% and then lowering the result by 11% ends at 12.8427, because the second 11% is taken of a bigger number.
