How to work it out

  1. Turn the percentage into a decimal: 38 ÷ 100 = 0.38
  2. Multiply: 0.38 × 66 = 25.08
  3. Check: Work backwards: 25.08 ÷ 66 × 100 = 38%.

Another method. As a proportion of part to whole: 38/100 = part/66, so part = 38 × 66 ÷ 100 = 25.08. Both methods always give the same answer.

In a spreadsheet: =38%*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

25.08 is the 38% share of 66. The remaining 62% is 40.92, and the two parts add back up to 66.

Discounts: 38% off an item priced $66 saves $25.08, so you pay $40.92.

Adding and taking away 38%

Increasing 66 by 38% gives 91.08 and decreasing it by 38% gives 40.92. These do not cancel out: raising 66 by 38% and then lowering the result by 38% ends at 56.4696, because the second 38% is taken of a bigger number.
