How to work it out

  1. Turn the percentage into a decimal: 70 ÷ 100 = 0.7
  2. Multiply: 0.7 × 57 = 39.9
  3. Check: Work backwards: 39.9 ÷ 57 × 100 = 70%.

Another method. As a proportion of part to whole: 70/100 = part/57, so part = 70 × 57 ÷ 100 = 39.9. Both methods always give the same answer.

In a spreadsheet: =70%*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

39.9 is the 70% share of 57. The remaining 30% is 17.1, and the two parts add back up to 57.

Discounts: 70% off an item priced $57 saves $39.9, so you pay $17.1.

Adding and taking away 70%

Increasing 57 by 70% gives 96.9 and decreasing it by 70% gives 17.1. These do not cancel out: raising 57 by 70% and then lowering the result by 70% ends at 29.07, because the second 70% is taken of a bigger number.
