How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 500 = 450
  3. Check: Work backwards: 450 ÷ 500 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/500, so part = 90 × 500 ÷ 100 = 450. Both methods always give the same answer.

In a spreadsheet: =90%*500. 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

450 is the 90% share of 500. The remaining 10% is 50, and the two parts add back up to 500.

Discounts: 90% off an item priced $500 saves $450, so you pay $50.

Adding and taking away 90%

Increasing 500 by 90% gives 950 and decreasing it by 90% gives 50. These do not cancel out: raising 500 by 90% and then lowering the result by 90% ends at 95, because the second 90% is taken of a bigger number.
