How to work it out

  1. Turn the percentage into a decimal: 83 ÷ 100 = 0.83
  2. Multiply: 0.83 × 13 = 10.79
  3. Check: Work backwards: 10.79 ÷ 13 × 100 = 83%.

Another method. As a proportion of part to whole: 83/100 = part/13, so part = 83 × 13 ÷ 100 = 10.79. Both methods always give the same answer.

In a spreadsheet: =83%*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

10.79 is the 83% share of 13. The remaining 17% is 2.21, and the two parts add back up to 13.

Discounts: 83% off an item priced $13 saves $10.79, so you pay $2.21.

Adding and taking away 83%

Increasing 13 by 83% gives 23.79 and decreasing it by 83% gives 2.21. These do not cancel out: raising 13 by 83% and then lowering the result by 83% ends at 4.0443, because the second 83% is taken of a bigger number.
