How to work it out

  1. Turn the percentage into a decimal: 7 ÷ 100 = 0.07
  2. Multiply: 0.07 × 51 = 3.57
  3. Check: Work backwards: 3.57 ÷ 51 × 100 = 7%.

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

In a spreadsheet: =7%*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

3.57 is the 7% share of 51. The remaining 93% is 47.43, and the two parts add back up to 51.

Discounts: 7% off an item priced $51 saves $3.57, so you pay $47.43.

Adding and taking away 7%

Increasing 51 by 7% gives 54.57 and decreasing it by 7% gives 47.43. These do not cancel out: raising 51 by 7% and then lowering the result by 7% ends at 50.7501, because the second 7% is taken of a bigger number.
