How to work it out

  1. Turn the percentage into a decimal: 42 ÷ 100 = 0.42
  2. Multiply: 0.42 × 75 = 31.5
  3. Check: Work backwards: 31.5 ÷ 75 × 100 = 42%.

Another method. As a proportion of part to whole: 42/100 = part/75, so part = 42 × 75 ÷ 100 = 31.5. Both methods always give the same answer.

In a spreadsheet: =42%*75. 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

31.5 is the 42% share of 75. The remaining 58% is 43.5, and the two parts add back up to 75.

Discounts: 42% off an item priced $75 saves $31.5, so you pay $43.5.

Adding and taking away 42%

Increasing 75 by 42% gives 106.5 and decreasing it by 42% gives 43.5. These do not cancel out: raising 75 by 42% and then lowering the result by 42% ends at 61.77, because the second 42% is taken of a bigger number.
