How to work it out

  1. Turn the percentage into a decimal: 9 ÷ 100 = 0.09
  2. Multiply: 0.09 × 57 = 5.13
  3. Check: Work backwards: 5.13 ÷ 57 × 100 = 9%.

Another method. As a proportion of part to whole: 9/100 = part/57, so part = 9 × 57 ÷ 100 = 5.13. Both methods always give the same answer.

In a spreadsheet: =9%*57. 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

5.13 is the 9% share of 57. The remaining 91% is 51.87, and the two parts add back up to 57.

Discounts: 9% off an item priced $57 saves $5.13, so you pay $51.87.

Adding and taking away 9%

Increasing 57 by 9% gives 62.13 and decreasing it by 9% gives 51.87. These do not cancel out: raising 57 by 9% and then lowering the result by 9% ends at 56.5383, because the second 9% is taken of a bigger number.
