How to work it out

  1. Turn the percentage into a decimal: 51 ÷ 100 = 0.51
  2. Multiply: 0.51 × 83 = 42.33
  3. Check: Work backwards: 42.33 ÷ 83 × 100 = 51%.

Another method. As a proportion of part to whole: 51/100 = part/83, so part = 51 × 83 ÷ 100 = 42.33. Both methods always give the same answer.

In a spreadsheet: =51%*83. 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

42.33 is the 51% share of 83. The remaining 49% is 40.67, and the two parts add back up to 83.

Discounts: 51% off an item priced $83 saves $42.33, so you pay $40.67.

Adding and taking away 51%

Increasing 83 by 51% gives 125.33 and decreasing it by 51% gives 40.67. These do not cancel out: raising 83 by 51% and then lowering the result by 51% ends at 61.4117, because the second 51% is taken of a bigger number.
