How to work it out

  1. Turn the percentage into a decimal: 85 ÷ 100 = 0.85
  2. Multiply: 0.85 × 42 = 35.7
  3. Check: Work backwards: 35.7 ÷ 42 × 100 = 85%.

Another method. As a proportion of part to whole: 85/100 = part/42, so part = 85 × 42 ÷ 100 = 35.7. Both methods always give the same answer.

In a spreadsheet: =85%*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

35.7 is the 85% share of 42. The remaining 15% is 6.3, and the two parts add back up to 42.

Discounts: 85% off an item priced $42 saves $35.7, so you pay $6.3.

Adding and taking away 85%

Increasing 42 by 85% gives 77.7 and decreasing it by 85% gives 6.3. These do not cancel out: raising 42 by 85% and then lowering the result by 85% ends at 11.655, because the second 85% is taken of a bigger number.
