How to work it out

  1. Turn the percentage into a decimal: 30 ÷ 100 = 0.3
  2. Multiply: 0.3 × 19 = 5.7
  3. Check: Work backwards: 5.7 ÷ 19 × 100 = 30%.

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

In a spreadsheet: =30%*19. 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 30% share of 19. The remaining 70% is 13.3, and the two parts add back up to 19.

Discounts: 30% off an item priced $19 saves $5.7, so you pay $13.3.

Adding and taking away 30%

Increasing 19 by 30% gives 24.7 and decreasing it by 30% gives 13.3. These do not cancel out: raising 19 by 30% and then lowering the result by 30% ends at 17.29, because the second 30% is taken of a bigger number.
