How to work it out

  1. Turn the percentage into a decimal: 51 ÷ 100 = 0.51
  2. Multiply: 0.51 × 77 = 39.27
  3. Check: Work backwards: 39.27 ÷ 77 × 100 = 51%.

Another method. As a proportion of part to whole: 51/100 = part/77, so part = 51 × 77 ÷ 100 = 39.27. Both methods always give the same answer.

In a spreadsheet: =51%*77. 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

39.27 is the 51% share of 77. The remaining 49% is 37.73, and the two parts add back up to 77.

Discounts: 51% off an item priced $77 saves $39.27, so you pay $37.73.

Adding and taking away 51%

Increasing 77 by 51% gives 116.27 and decreasing it by 51% gives 37.73. These do not cancel out: raising 77 by 51% and then lowering the result by 51% ends at 56.9723, because the second 51% is taken of a bigger number.
