How to work it out

  1. Turn the percentage into a decimal: 9 ÷ 100 = 0.09
  2. Multiply: 0.09 × 17 = 1.53
  3. Check: Work backwards: 1.53 ÷ 17 × 100 = 9%.

Another method. As a proportion of part to whole: 9/100 = part/17, so part = 9 × 17 ÷ 100 = 1.53. Both methods always give the same answer.

In a spreadsheet: =9%*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

1.53 is the 9% share of 17. The remaining 91% is 15.47, and the two parts add back up to 17.

Discounts: 9% off an item priced $17 saves $1.53, so you pay $15.47.

Adding and taking away 9%

Increasing 17 by 9% gives 18.53 and decreasing it by 9% gives 15.47. These do not cancel out: raising 17 by 9% and then lowering the result by 9% ends at 16.8623, because the second 9% is taken of a bigger number.
