How to work it out

  1. Turn the percentage into a decimal: 3 ÷ 100 = 0.03
  2. Multiply: 0.03 × 51 = 1.53
  3. Check: Work backwards: 1.53 ÷ 51 × 100 = 3%.

Another method. As a proportion of part to whole: 3/100 = part/51, so part = 3 × 51 ÷ 100 = 1.53. Both methods always give the same answer.

In a spreadsheet: =3%*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

1.53 is the 3% share of 51. The remaining 97% is 49.47, and the two parts add back up to 51.

Discounts: 3% off an item priced $51 saves $1.53, so you pay $49.47.

Adding and taking away 3%

Increasing 51 by 3% gives 52.53 and decreasing it by 3% gives 49.47. These do not cancel out: raising 51 by 3% and then lowering the result by 3% ends at 50.9541, because the second 3% is taken of a bigger number.
