How to work it out

  1. Turn the percentage into a decimal: 40 ÷ 100 = 0.4
  2. Multiply: 0.4 × 225 = 90
  3. Check: Work backwards: 90 ÷ 225 × 100 = 40%.

Another method. As a proportion of part to whole: 40/100 = part/225, so part = 40 × 225 ÷ 100 = 90. Both methods always give the same answer.

In a spreadsheet: =40%*225. 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

90 is the 40% share of 225. The remaining 60% is 135, and the two parts add back up to 225.

Discounts: 40% off an item priced $225 saves $90, so you pay $135.

Adding and taking away 40%

Increasing 225 by 40% gives 315 and decreasing it by 40% gives 135. These do not cancel out: raising 225 by 40% and then lowering the result by 40% ends at 189, because the second 40% is taken of a bigger number.
