How to work it out

  1. Turn the percentage into a decimal: 42 ÷ 100 = 0.42
  2. Multiply: 0.42 × 13 = 5.46
  3. Check: Work backwards: 5.46 ÷ 13 × 100 = 42%.

Another method. As a proportion of part to whole: 42/100 = part/13, so part = 42 × 13 ÷ 100 = 5.46. Both methods always give the same answer.

In a spreadsheet: =42%*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

5.46 is the 42% share of 13. The remaining 58% is 7.54, and the two parts add back up to 13.

Discounts: 42% off an item priced $13 saves $5.46, so you pay $7.54.

Adding and taking away 42%

Increasing 13 by 42% gives 18.46 and decreasing it by 42% gives 7.54. These do not cancel out: raising 13 by 42% and then lowering the result by 42% ends at 10.7068, because the second 42% is taken of a bigger number.
