How to work it out

  1. Turn the percentage into a decimal: 80 ÷ 100 = 0.8
  2. Multiply: 0.8 × 125 = 100
  3. Check: Work backwards: 100 ÷ 125 × 100 = 80%.

Another method. As a proportion of part to whole: 80/100 = part/125, so part = 80 × 125 ÷ 100 = 100. Both methods always give the same answer.

In a spreadsheet: =80%*125. 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

100 is the 80% share of 125. The remaining 20% is 25, and the two parts add back up to 125.

Discounts: 80% off an item priced $125 saves $100, so you pay $25.

Adding and taking away 80%

Increasing 125 by 80% gives 225 and decreasing it by 80% gives 25. These do not cancel out: raising 125 by 80% and then lowering the result by 80% ends at 45, because the second 80% is taken of a bigger number.
