How to work it out

  1. Turn the percentage into a decimal: 80 ÷ 100 = 0.8
  2. Multiply: 0.8 × 38 = 30.4
  3. Check: Work backwards: 30.4 ÷ 38 × 100 = 80%.

Another method. As a proportion of part to whole: 80/100 = part/38, so part = 80 × 38 ÷ 100 = 30.4. Both methods always give the same answer.

In a spreadsheet: =80%*38. 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

30.4 is the 80% share of 38. The remaining 20% is 7.6, and the two parts add back up to 38.

Discounts: 80% off an item priced $38 saves $30.4, so you pay $7.6.

Adding and taking away 80%

Increasing 38 by 80% gives 68.4 and decreasing it by 80% gives 7.6. These do not cancel out: raising 38 by 80% and then lowering the result by 80% ends at 13.68, because the second 80% is taken of a bigger number.
