How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 250 = 225
  3. Check: Work backwards: 225 ÷ 250 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/250, so part = 90 × 250 ÷ 100 = 225. Both methods always give the same answer.

In a spreadsheet: =90%*250. 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

225 is the 90% share of 250. The remaining 10% is 25, and the two parts add back up to 250.

Discounts: 90% off an item priced $250 saves $225, so you pay $25.

Adding and taking away 90%

Increasing 250 by 90% gives 475 and decreasing it by 90% gives 25. These do not cancel out: raising 250 by 90% and then lowering the result by 90% ends at 47.5, because the second 90% is taken of a bigger number.
