How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 75 = 67.5
  3. Check: Work backwards: 67.5 ÷ 75 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/75, so part = 90 × 75 ÷ 100 = 67.5. Both methods always give the same answer.

In a spreadsheet: =90%*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

67.5 is the 90% share of 75. The remaining 10% is 7.5, and the two parts add back up to 75.

Discounts: 90% off an item priced $75 saves $67.5, so you pay $7.5.

Adding and taking away 90%

Increasing 75 by 90% gives 142.5 and decreasing it by 90% gives 7.5. These do not cancel out: raising 75 by 90% and then lowering the result by 90% ends at 14.25, because the second 90% is taken of a bigger number.
