How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 65 = 20.15
  3. Check: Work backwards: 20.15 ÷ 65 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/65, so part = 31 × 65 ÷ 100 = 20.15. Both methods always give the same answer.

In a spreadsheet: =31%*65. 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

20.15 is the 31% share of 65. The remaining 69% is 44.85, and the two parts add back up to 65.

Discounts: 31% off an item priced $65 saves $20.15, so you pay $44.85.

Adding and taking away 31%

Increasing 65 by 31% gives 85.15 and decreasing it by 31% gives 44.85. These do not cancel out: raising 65 by 31% and then lowering the result by 31% ends at 58.7535, because the second 31% is taken of a bigger number.
