How to work it out

  1. Turn the percentage into a decimal: 65 ÷ 100 = 0.65
  2. Multiply: 0.65 × 13 = 8.45
  3. Check: Work backwards: 8.45 ÷ 13 × 100 = 65%.

Another method. As a proportion of part to whole: 65/100 = part/13, so part = 65 × 13 ÷ 100 = 8.45. Both methods always give the same answer.

In a spreadsheet: =65%*13. 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

8.45 is the 65% share of 13. The remaining 35% is 4.55, and the two parts add back up to 13.

Discounts: 65% off an item priced $13 saves $8.45, so you pay $4.55.

Adding and taking away 65%

Increasing 13 by 65% gives 21.45 and decreasing it by 65% gives 4.55. These do not cancel out: raising 13 by 65% and then lowering the result by 65% ends at 7.5075, because the second 65% is taken of a bigger number.
