How to work it out

  1. Turn the percentage into a decimal: 57 ÷ 100 = 0.57
  2. Multiply: 0.57 × 20 = 11.4
  3. Check: Work backwards: 11.4 ÷ 20 × 100 = 57%.

Another method. As a proportion of part to whole: 57/100 = part/20, so part = 57 × 20 ÷ 100 = 11.4. Both methods always give the same answer.

In a spreadsheet: =57%*20. 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

11.4 is the 57% share of 20. The remaining 43% is 8.6, and the two parts add back up to 20.

Discounts: 57% off an item priced $20 saves $11.4, so you pay $8.6.

Adding and taking away 57%

Increasing 20 by 57% gives 31.4 and decreasing it by 57% gives 8.6. These do not cancel out: raising 20 by 57% and then lowering the result by 57% ends at 13.502, because the second 57% is taken of a bigger number.
