How to work it out

  1. Turn the percentage into a decimal: 19 ÷ 100 = 0.19
  2. Multiply: 0.19 × 30 = 5.7
  3. Check: Work backwards: 5.7 ÷ 30 × 100 = 19%.

Another method. As a proportion of part to whole: 19/100 = part/30, so part = 19 × 30 ÷ 100 = 5.7. Both methods always give the same answer.

In a spreadsheet: =19%*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

5.7 is the 19% share of 30. The remaining 81% is 24.3, and the two parts add back up to 30.

Discounts: 19% off an item priced $30 saves $5.7, so you pay $24.3.

Adding and taking away 19%

Increasing 30 by 19% gives 35.7 and decreasing it by 19% gives 24.3. These do not cancel out: raising 30 by 19% and then lowering the result by 19% ends at 28.917, because the second 19% is taken of a bigger number.
