How to work it out

  1. Turn the percentage into a decimal: 99 ÷ 100 = 0.99
  2. Multiply: 0.99 × 39 = 38.61
  3. Check: Work backwards: 38.61 ÷ 39 × 100 = 99%.

Another method. As a proportion of part to whole: 99/100 = part/39, so part = 99 × 39 ÷ 100 = 38.61. Both methods always give the same answer.

In a spreadsheet: =99%*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

38.61 is the 99% share of 39. The remaining 1% is 0.39, and the two parts add back up to 39.

Discounts: 99% off an item priced $39 saves $38.61, so you pay $0.39.

Adding and taking away 99%

Increasing 39 by 99% gives 77.61 and decreasing it by 99% gives 0.39. These do not cancel out: raising 39 by 99% and then lowering the result by 99% ends at 0.7761, because the second 99% is taken of a bigger number.
