How to work it out

  1. Turn the percentage into a decimal: 33 ÷ 100 = 0.33
  2. Multiply: 0.33 × 13 = 4.29
  3. Check: Work backwards: 4.29 ÷ 13 × 100 = 33%.

Another method. As a proportion of part to whole: 33/100 = part/13, so part = 33 × 13 ÷ 100 = 4.29. Both methods always give the same answer.

In a spreadsheet: =33%*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

4.29 is the 33% share of 13. The remaining 67% is 8.71, and the two parts add back up to 13.

Discounts: 33% off an item priced $13 saves $4.29, so you pay $8.71.

Adding and taking away 33%

Increasing 13 by 33% gives 17.29 and decreasing it by 33% gives 8.71. These do not cancel out: raising 13 by 33% and then lowering the result by 33% ends at 11.5843, because the second 33% is taken of a bigger number.
