How to work it out

  1. Turn the percentage into a decimal: 51 ÷ 100 = 0.51
  2. Multiply: 0.51 × 84 = 42.84
  3. Check: Work backwards: 42.84 ÷ 84 × 100 = 51%.

Another method. As a proportion of part to whole: 51/100 = part/84, so part = 51 × 84 ÷ 100 = 42.84. Both methods always give the same answer.

In a spreadsheet: =51%*84. 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

42.84 is the 51% share of 84. The remaining 49% is 41.16, and the two parts add back up to 84.

Discounts: 51% off an item priced $84 saves $42.84, so you pay $41.16.

Adding and taking away 51%

Increasing 84 by 51% gives 126.84 and decreasing it by 51% gives 41.16. These do not cancel out: raising 84 by 51% and then lowering the result by 51% ends at 62.1516, because the second 51% is taken of a bigger number.
