How to work it out

  1. Turn the percentage into a decimal: 51 ÷ 100 = 0.51
  2. Multiply: 0.51 × 79 = 40.29
  3. Check: Work backwards: 40.29 ÷ 79 × 100 = 51%.

Another method. As a proportion of part to whole: 51/100 = part/79, so part = 51 × 79 ÷ 100 = 40.29. Both methods always give the same answer.

In a spreadsheet: =51%*79. 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

40.29 is the 51% share of 79. The remaining 49% is 38.71, and the two parts add back up to 79.

Discounts: 51% off an item priced $79 saves $40.29, so you pay $38.71.

Adding and taking away 51%

Increasing 79 by 51% gives 119.29 and decreasing it by 51% gives 38.71. These do not cancel out: raising 79 by 51% and then lowering the result by 51% ends at 58.4521, because the second 51% is taken of a bigger number.
