How to work it out

  1. Turn the percentage into a decimal: 3 ÷ 100 = 0.03
  2. Multiply: 0.03 × 78 = 2.34
  3. Check: Work backwards: 2.34 ÷ 78 × 100 = 3%.

Another method. As a proportion of part to whole: 3/100 = part/78, so part = 3 × 78 ÷ 100 = 2.34. Both methods always give the same answer.

In a spreadsheet: =3%*78. 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

2.34 is the 3% share of 78. The remaining 97% is 75.66, and the two parts add back up to 78.

Discounts: 3% off an item priced $78 saves $2.34, so you pay $75.66.

Adding and taking away 3%

Increasing 78 by 3% gives 80.34 and decreasing it by 3% gives 75.66. These do not cancel out: raising 78 by 3% and then lowering the result by 3% ends at 77.9298, because the second 3% is taken of a bigger number.
