How to work it out

  1. Turn the percentage into a decimal: 83 ÷ 100 = 0.83
  2. Multiply: 0.83 × 45 = 37.35
  3. Check: Work backwards: 37.35 ÷ 45 × 100 = 83%.

Another method. As a proportion of part to whole: 83/100 = part/45, so part = 83 × 45 ÷ 100 = 37.35. Both methods always give the same answer.

In a spreadsheet: =83%*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

37.35 is the 83% share of 45. The remaining 17% is 7.65, and the two parts add back up to 45.

Discounts: 83% off an item priced $45 saves $37.35, so you pay $7.65.

Adding and taking away 83%

Increasing 45 by 83% gives 82.35 and decreasing it by 83% gives 7.65. These do not cancel out: raising 45 by 83% and then lowering the result by 83% ends at 13.9995, because the second 83% is taken of a bigger number.
