How to work it out

  1. Turn the percentage into a decimal: 25 ÷ 100 = 0.25
  2. Multiply: 0.25 × 39 = 9.75
  3. Check: Work backwards: 9.75 ÷ 39 × 100 = 25%.

Another method. As a proportion of part to whole: 25/100 = part/39, so part = 25 × 39 ÷ 100 = 9.75. Both methods always give the same answer.

In a spreadsheet: =25%*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

9.75 is the 25% share of 39. The remaining 75% is 29.25, and the two parts add back up to 39.

Discounts: 25% off an item priced $39 saves $9.75, so you pay $29.25.

Adding and taking away 25%

Increasing 39 by 25% gives 48.75 and decreasing it by 25% gives 29.25. These do not cancel out: raising 39 by 25% and then lowering the result by 25% ends at 36.5625, because the second 25% is taken of a bigger number.
