How to work it out

  1. Turn the percentage into a decimal: 70 ÷ 100 = 0.7
  2. Multiply: 0.7 × 13 = 9.1
  3. Check: Work backwards: 9.1 ÷ 13 × 100 = 70%.

Another method. As a proportion of part to whole: 70/100 = part/13, so part = 70 × 13 ÷ 100 = 9.1. Both methods always give the same answer.

In a spreadsheet: =70%*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

9.1 is the 70% share of 13. The remaining 30% is 3.9, and the two parts add back up to 13.

Discounts: 70% off an item priced $13 saves $9.1, so you pay $3.9.

Adding and taking away 70%

Increasing 13 by 70% gives 22.1 and decreasing it by 70% gives 3.9. These do not cancel out: raising 13 by 70% and then lowering the result by 70% ends at 6.63, because the second 70% is taken of a bigger number.
