How to work it out

  1. Turn the percentage into a decimal: 45 ÷ 100 = 0.45
  2. Multiply: 0.45 × 75 = 33.75
  3. Check: Work backwards: 33.75 ÷ 75 × 100 = 45%.

Another method. As a proportion of part to whole: 45/100 = part/75, so part = 45 × 75 ÷ 100 = 33.75. Both methods always give the same answer.

In a spreadsheet: =45%*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

33.75 is the 45% share of 75. The remaining 55% is 41.25, and the two parts add back up to 75.

Discounts: 45% off an item priced $75 saves $33.75, so you pay $41.25.

Adding and taking away 45%

Increasing 75 by 45% gives 108.75 and decreasing it by 45% gives 41.25. These do not cancel out: raising 75 by 45% and then lowering the result by 45% ends at 59.8125, because the second 45% is taken of a bigger number.
