How to work it out

  1. Turn the percentage into a decimal: 89 ÷ 100 = 0.89
  2. Multiply: 0.89 × 42 = 37.38
  3. Check: Work backwards: 37.38 ÷ 42 × 100 = 89%.

Another method. As a proportion of part to whole: 89/100 = part/42, so part = 89 × 42 ÷ 100 = 37.38. Both methods always give the same answer.

In a spreadsheet: =89%*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

37.38 is the 89% share of 42. The remaining 11% is 4.62, and the two parts add back up to 42.

Discounts: 89% off an item priced $42 saves $37.38, so you pay $4.62.

Adding and taking away 89%

Increasing 42 by 89% gives 79.38 and decreasing it by 89% gives 4.62. These do not cancel out: raising 42 by 89% and then lowering the result by 89% ends at 8.7318, because the second 89% is taken of a bigger number.
