How to work it out

  1. Turn the percentage into a decimal: 82 ÷ 100 = 0.82
  2. Multiply: 0.82 × 42 = 34.44
  3. Check: Work backwards: 34.44 ÷ 42 × 100 = 82%.

Another method. As a proportion of part to whole: 82/100 = part/42, so part = 82 × 42 ÷ 100 = 34.44. Both methods always give the same answer.

In a spreadsheet: =82%*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

34.44 is the 82% share of 42. The remaining 18% is 7.56, and the two parts add back up to 42.

Discounts: 82% off an item priced $42 saves $34.44, so you pay $7.56.

Adding and taking away 82%

Increasing 42 by 82% gives 76.44 and decreasing it by 82% gives 7.56. These do not cancel out: raising 42 by 82% and then lowering the result by 82% ends at 13.7592, because the second 82% is taken of a bigger number.
