How to work it out

  1. Turn the percentage into a decimal: 42 ÷ 100 = 0.42
  2. Multiply: 0.42 × 39 = 16.38
  3. Check: Work backwards: 16.38 ÷ 39 × 100 = 42%.

Another method. As a proportion of part to whole: 42/100 = part/39, so part = 42 × 39 ÷ 100 = 16.38. Both methods always give the same answer.

In a spreadsheet: =42%*39. 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

16.38 is the 42% share of 39. The remaining 58% is 22.62, and the two parts add back up to 39.

Discounts: 42% off an item priced $39 saves $16.38, so you pay $22.62.

Adding and taking away 42%

Increasing 39 by 42% gives 55.38 and decreasing it by 42% gives 22.62. These do not cancel out: raising 39 by 42% and then lowering the result by 42% ends at 32.1204, because the second 42% is taken of a bigger number.
