How to work it out

  1. Turn the percentage into a decimal: 3 ÷ 100 = 0.03
  2. Multiply: 0.03 × 84 = 2.52
  3. Check: Work backwards: 2.52 ÷ 84 × 100 = 3%.

Another method. As a proportion of part to whole: 3/100 = part/84, so part = 3 × 84 ÷ 100 = 2.52. Both methods always give the same answer.

In a spreadsheet: =3%*84. 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

2.52 is the 3% share of 84. The remaining 97% is 81.48, and the two parts add back up to 84.

Discounts: 3% off an item priced $84 saves $2.52, so you pay $81.48.

Adding and taking away 3%

Increasing 84 by 3% gives 86.52 and decreasing it by 3% gives 81.48. These do not cancel out: raising 84 by 3% and then lowering the result by 3% ends at 83.9244, because the second 3% is taken of a bigger number.
