How to work it out

  1. Turn the percentage into a decimal: 75 ÷ 100 = 0.75
  2. Multiply: 0.75 × 90 = 67.5
  3. Check: Work backwards: 67.5 ÷ 90 × 100 = 75%.

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

In a spreadsheet: =75%*90. 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 75% share of 90. The remaining 25% is 22.5, and the two parts add back up to 90.

Discounts: 75% off an item priced $90 saves $67.5, so you pay $22.5.

Adding and taking away 75%

Increasing 90 by 75% gives 157.5 and decreasing it by 75% gives 22.5. These do not cancel out: raising 90 by 75% and then lowering the result by 75% ends at 39.375, because the second 75% is taken of a bigger number.
