How to work it out

  1. Turn the percentage into a decimal: 82 ÷ 100 = 0.82
  2. Multiply: 0.82 × 51 = 41.82
  3. Check: Work backwards: 41.82 ÷ 51 × 100 = 82%.

Another method. As a proportion of part to whole: 82/100 = part/51, so part = 82 × 51 ÷ 100 = 41.82. Both methods always give the same answer.

In a spreadsheet: =82%*51. 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

41.82 is the 82% share of 51. The remaining 18% is 9.18, and the two parts add back up to 51.

Discounts: 82% off an item priced $51 saves $41.82, so you pay $9.18.

Adding and taking away 82%

Increasing 51 by 82% gives 92.82 and decreasing it by 82% gives 9.18. These do not cancel out: raising 51 by 82% and then lowering the result by 82% ends at 16.7076, because the second 82% is taken of a bigger number.
