How to work it out

  1. Turn the percentage into a decimal: 10 ÷ 100 = 0.1
  2. Multiply: 0.1 × 200 = 20
  3. Check: Work backwards: 20 ÷ 200 × 100 = 10%.

Another method. As a proportion of part to whole: 10/100 = part/200, so part = 10 × 200 ÷ 100 = 20. Both methods always give the same answer.

In a spreadsheet: =10%*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

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

Discounts: 10% off an item priced $200 saves $20, so you pay $180.

Adding and taking away 10%

Increasing 200 by 10% gives 220 and decreasing it by 10% gives 180. These do not cancel out: raising 200 by 10% and then lowering the result by 10% ends at 198, because the second 10% is taken of a bigger number.
