How to work it out

  1. Turn the percentage into a decimal: 51 ÷ 100 = 0.51
  2. Multiply: 0.51 × 7 = 3.57
  3. Check: Work backwards: 3.57 ÷ 7 × 100 = 51%.

Another method. As a proportion of part to whole: 51/100 = part/7, so part = 51 × 7 ÷ 100 = 3.57. Both methods always give the same answer.

In a spreadsheet: =51%*7. 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

3.57 is the 51% share of 7. The remaining 49% is 3.43, and the two parts add back up to 7.

Discounts: 51% off an item priced $7 saves $3.57, so you pay $3.43.

Adding and taking away 51%

Increasing 7 by 51% gives 10.57 and decreasing it by 51% gives 3.43. These do not cancel out: raising 7 by 51% and then lowering the result by 51% ends at 5.1793, because the second 51% is taken of a bigger number.
