How to work it out

  1. Turn the percentage into a decimal: 64 ÷ 100 = 0.64
  2. Multiply: 0.64 × 13 = 8.32
  3. Check: Work backwards: 8.32 ÷ 13 × 100 = 64%.

Another method. As a proportion of part to whole: 64/100 = part/13, so part = 64 × 13 ÷ 100 = 8.32. Both methods always give the same answer.

In a spreadsheet: =64%*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

8.32 is the 64% share of 13. The remaining 36% is 4.68, and the two parts add back up to 13.

Discounts: 64% off an item priced $13 saves $8.32, so you pay $4.68.

Adding and taking away 64%

Increasing 13 by 64% gives 21.32 and decreasing it by 64% gives 4.68. These do not cancel out: raising 13 by 64% and then lowering the result by 64% ends at 7.6752, because the second 64% is taken of a bigger number.
