How to work it out

  1. Turn the percentage into a decimal: 38 ÷ 100 = 0.38
  2. Multiply: 0.38 × 78 = 29.64
  3. Check: Work backwards: 29.64 ÷ 78 × 100 = 38%.

Another method. As a proportion of part to whole: 38/100 = part/78, so part = 38 × 78 ÷ 100 = 29.64. Both methods always give the same answer.

In a spreadsheet: =38%*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

29.64 is the 38% share of 78. The remaining 62% is 48.36, and the two parts add back up to 78.

Discounts: 38% off an item priced $78 saves $29.64, so you pay $48.36.

Adding and taking away 38%

Increasing 78 by 38% gives 107.64 and decreasing it by 38% gives 48.36. These do not cancel out: raising 78 by 38% and then lowering the result by 38% ends at 66.7368, because the second 38% is taken of a bigger number.
