How to work it out

  1. Turn the percentage into a decimal: 38 ÷ 100 = 0.38
  2. Multiply: 0.38 × 30 = 11.4
  3. Check: Work backwards: 11.4 ÷ 30 × 100 = 38%.

Another method. As a proportion of part to whole: 38/100 = part/30, so part = 38 × 30 ÷ 100 = 11.4. Both methods always give the same answer.

In a spreadsheet: =38%*30. 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

11.4 is the 38% share of 30. The remaining 62% is 18.6, and the two parts add back up to 30.

Discounts: 38% off an item priced $30 saves $11.4, so you pay $18.6.

Adding and taking away 38%

Increasing 30 by 38% gives 41.4 and decreasing it by 38% gives 18.6. These do not cancel out: raising 30 by 38% and then lowering the result by 38% ends at 25.668, because the second 38% is taken of a bigger number.
