How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 200 = 180
  3. Check: Work backwards: 180 ÷ 200 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/200, so part = 90 × 200 ÷ 100 = 180. Both methods always give the same answer.

In a spreadsheet: =90%*200. 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

180 is the 90% share of 200. The remaining 10% is 20, and the two parts add back up to 200.

Discounts: 90% off an item priced $200 saves $180, so you pay $20.

Adding and taking away 90%

Increasing 200 by 90% gives 380 and decreasing it by 90% gives 20. These do not cancel out: raising 200 by 90% and then lowering the result by 90% ends at 38, because the second 90% is taken of a bigger number.
