How to work it out

  1. Turn the percentage into a decimal: 12 ÷ 100 = 0.12
  2. Multiply: 0.12 × 39 = 4.68
  3. Check: Work backwards: 4.68 ÷ 39 × 100 = 12%.

Another method. As a proportion of part to whole: 12/100 = part/39, so part = 12 × 39 ÷ 100 = 4.68. Both methods always give the same answer.

In a spreadsheet: =12%*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

4.68 is the 12% share of 39. The remaining 88% is 34.32, and the two parts add back up to 39.

Discounts: 12% off an item priced $39 saves $4.68, so you pay $34.32.

Adding and taking away 12%

Increasing 39 by 12% gives 43.68 and decreasing it by 12% gives 34.32. These do not cancel out: raising 39 by 12% and then lowering the result by 12% ends at 38.4384, because the second 12% is taken of a bigger number.
