How to work it out

  1. Turn the percentage into a decimal: 10 ÷ 100 = 0.1
  2. Multiply: 0.1 × 82 = 8.2
  3. Check: Work backwards: 8.2 ÷ 82 × 100 = 10%.

Another method. As a proportion of part to whole: 10/100 = part/82, so part = 10 × 82 ÷ 100 = 8.2. Both methods always give the same answer.

In a spreadsheet: =10%*82. 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

8.2 is the 10% share of 82. The remaining 90% is 73.8, and the two parts add back up to 82.

Discounts: 10% off an item priced $82 saves $8.2, so you pay $73.8.

Adding and taking away 10%

Increasing 82 by 10% gives 90.2 and decreasing it by 10% gives 73.8. These do not cancel out: raising 82 by 10% and then lowering the result by 10% ends at 81.18, because the second 10% is taken of a bigger number.
