How to work it out

  1. Turn the percentage into a decimal: 17 ÷ 100 = 0.17
  2. Multiply: 0.17 × 42 = 7.14
  3. Check: Work backwards: 7.14 ÷ 42 × 100 = 17%.

Another method. As a proportion of part to whole: 17/100 = part/42, so part = 17 × 42 ÷ 100 = 7.14. Both methods always give the same answer.

In a spreadsheet: =17%*42. 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

7.14 is the 17% share of 42. The remaining 83% is 34.86, and the two parts add back up to 42.

Discounts: 17% off an item priced $42 saves $7.14, so you pay $34.86.

Adding and taking away 17%

Increasing 42 by 17% gives 49.14 and decreasing it by 17% gives 34.86. These do not cancel out: raising 42 by 17% and then lowering the result by 17% ends at 40.7862, because the second 17% is taken of a bigger number.
