How to work it out

  1. Turn the percentage into a decimal: 3 ÷ 100 = 0.03
  2. Multiply: 0.03 × 17 = 0.51
  3. Check: Work backwards: 0.51 ÷ 17 × 100 = 3%.

Another method. As a proportion of part to whole: 3/100 = part/17, so part = 3 × 17 ÷ 100 = 0.51. Both methods always give the same answer.

In a spreadsheet: =3%*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

0.51 is the 3% share of 17. The remaining 97% is 16.49, and the two parts add back up to 17.

Discounts: 3% off an item priced $17 saves $0.51, so you pay $16.49.

Adding and taking away 3%

Increasing 17 by 3% gives 17.51 and decreasing it by 3% gives 16.49. These do not cancel out: raising 17 by 3% and then lowering the result by 3% ends at 16.9847, because the second 3% is taken of a bigger number.
