How to work it out

  1. Turn the percentage into a decimal: 40 ÷ 100 = 0.4
  2. Multiply: 0.4 × 125 = 50
  3. Check: Work backwards: 50 ÷ 125 × 100 = 40%.

Another method. As a proportion of part to whole: 40/100 = part/125, so part = 40 × 125 ÷ 100 = 50. Both methods always give the same answer.

In a spreadsheet: =40%*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

50 is the 40% share of 125. The remaining 60% is 75, and the two parts add back up to 125.

Discounts: 40% off an item priced $125 saves $50, so you pay $75.

Adding and taking away 40%

Increasing 125 by 40% gives 175 and decreasing it by 40% gives 75. These do not cancel out: raising 125 by 40% and then lowering the result by 40% ends at 105, because the second 40% is taken of a bigger number.
