How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 17 = 13.26
  3. Check: Work backwards: 13.26 ÷ 17 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/17, so part = 78 × 17 ÷ 100 = 13.26. Both methods always give the same answer.

In a spreadsheet: =78%*17. 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

13.26 is the 78% share of 17. The remaining 22% is 3.74, and the two parts add back up to 17.

Discounts: 78% off an item priced $17 saves $13.26, so you pay $3.74.

Adding and taking away 78%

Increasing 17 by 78% gives 30.26 and decreasing it by 78% gives 3.74. These do not cancel out: raising 17 by 78% and then lowering the result by 78% ends at 6.6572, because the second 78% is taken of a bigger number.
