How to work it out

  1. Turn the percentage into a decimal: 8 ÷ 100 = 0.08
  2. Multiply: 0.08 × 51 = 4.08
  3. Check: Work backwards: 4.08 ÷ 51 × 100 = 8%.

Another method. As a proportion of part to whole: 8/100 = part/51, so part = 8 × 51 ÷ 100 = 4.08. Both methods always give the same answer.

In a spreadsheet: =8%*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

4.08 is the 8% share of 51. The remaining 92% is 46.92, and the two parts add back up to 51.

Discounts: 8% off an item priced $51 saves $4.08, so you pay $46.92.

Adding and taking away 8%

Increasing 51 by 8% gives 55.08 and decreasing it by 8% gives 46.92. These do not cancel out: raising 51 by 8% and then lowering the result by 8% ends at 50.6736, because the second 8% is taken of a bigger number.
