How to work it out

  1. Turn the percentage into a decimal: 82 ÷ 100 = 0.82
  2. Multiply: 0.82 × 45 = 36.9
  3. Check: Work backwards: 36.9 ÷ 45 × 100 = 82%.

Another method. As a proportion of part to whole: 82/100 = part/45, so part = 82 × 45 ÷ 100 = 36.9. Both methods always give the same answer.

In a spreadsheet: =82%*45. 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

36.9 is the 82% share of 45. The remaining 18% is 8.1, and the two parts add back up to 45.

Discounts: 82% off an item priced $45 saves $36.9, so you pay $8.1.

Adding and taking away 82%

Increasing 45 by 82% gives 81.9 and decreasing it by 82% gives 8.1. These do not cancel out: raising 45 by 82% and then lowering the result by 82% ends at 14.742, because the second 82% is taken of a bigger number.
