How to work it out

  1. Turn the percentage into a decimal: 33 ÷ 100 = 0.33
  2. Multiply: 0.33 × 90 = 29.7
  3. Check: Work backwards: 29.7 ÷ 90 × 100 = 33%.

Another method. As a proportion of part to whole: 33/100 = part/90, so part = 33 × 90 ÷ 100 = 29.7. Both methods always give the same answer.

In a spreadsheet: =33%*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

29.7 is the 33% share of 90. The remaining 67% is 60.3, and the two parts add back up to 90.

Discounts: 33% off an item priced $90 saves $29.7, so you pay $60.3.

Adding and taking away 33%

Increasing 90 by 33% gives 119.7 and decreasing it by 33% gives 60.3. These do not cancel out: raising 90 by 33% and then lowering the result by 33% ends at 80.199, because the second 33% is taken of a bigger number.
