How to work it out

  1. Turn the percentage into a decimal: 3 ÷ 100 = 0.03
  2. Multiply: 0.03 × 66 = 1.98
  3. Check: Work backwards: 1.98 ÷ 66 × 100 = 3%.

Another method. As a proportion of part to whole: 3/100 = part/66, so part = 3 × 66 ÷ 100 = 1.98. Both methods always give the same answer.

In a spreadsheet: =3%*66. 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

1.98 is the 3% share of 66. The remaining 97% is 64.02, and the two parts add back up to 66.

Discounts: 3% off an item priced $66 saves $1.98, so you pay $64.02.

Adding and taking away 3%

Increasing 66 by 3% gives 67.98 and decreasing it by 3% gives 64.02. These do not cancel out: raising 66 by 3% and then lowering the result by 3% ends at 65.9406, because the second 3% is taken of a bigger number.
