How to work it out

  1. Turn the percentage into a decimal: 95 ÷ 100 = 0.95
  2. Multiply: 0.95 × 42 = 39.9
  3. Check: Work backwards: 39.9 ÷ 42 × 100 = 95%.

Another method. As a proportion of part to whole: 95/100 = part/42, so part = 95 × 42 ÷ 100 = 39.9. Both methods always give the same answer.

In a spreadsheet: =95%*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

39.9 is the 95% share of 42. The remaining 5% is 2.1, and the two parts add back up to 42.

Discounts: 95% off an item priced $42 saves $39.9, so you pay $2.1.

Adding and taking away 95%

Increasing 42 by 95% gives 81.9 and decreasing it by 95% gives 2.1. These do not cancel out: raising 42 by 95% and then lowering the result by 95% ends at 4.095, because the second 95% is taken of a bigger number.
