How to work it out

  1. Turn the percentage into a decimal: 8 ÷ 100 = 0.08
  2. Multiply: 0.08 × 57 = 4.56
  3. Check: Work backwards: 4.56 ÷ 57 × 100 = 8%.

Another method. As a proportion of part to whole: 8/100 = part/57, so part = 8 × 57 ÷ 100 = 4.56. Both methods always give the same answer.

In a spreadsheet: =8%*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

4.56 is the 8% share of 57. The remaining 92% is 52.44, and the two parts add back up to 57.

Discounts: 8% off an item priced $57 saves $4.56, so you pay $52.44.

Adding and taking away 8%

Increasing 57 by 8% gives 61.56 and decreasing it by 8% gives 52.44. These do not cancel out: raising 57 by 8% and then lowering the result by 8% ends at 56.6352, because the second 8% is taken of a bigger number.
