How to work it out

  1. Turn the percentage into a decimal: 57 ÷ 100 = 0.57
  2. Multiply: 0.57 × 80 = 45.6
  3. Check: Work backwards: 45.6 ÷ 80 × 100 = 57%.

Another method. As a proportion of part to whole: 57/100 = part/80, so part = 57 × 80 ÷ 100 = 45.6. Both methods always give the same answer.

In a spreadsheet: =57%*80. 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

45.6 is the 57% share of 80. The remaining 43% is 34.4, and the two parts add back up to 80.

Discounts: 57% off an item priced $80 saves $45.6, so you pay $34.4.

Adding and taking away 57%

Increasing 80 by 57% gives 125.6 and decreasing it by 57% gives 34.4. These do not cancel out: raising 80 by 57% and then lowering the result by 57% ends at 54.008, because the second 57% is taken of a bigger number.
