How to work it out

  1. Turn the percentage into a decimal: 80 ÷ 100 = 0.8
  2. Multiply: 0.8 × 19 = 15.2
  3. Check: Work backwards: 15.2 ÷ 19 × 100 = 80%.

Another method. As a proportion of part to whole: 80/100 = part/19, so part = 80 × 19 ÷ 100 = 15.2. Both methods always give the same answer.

In a spreadsheet: =80%*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

15.2 is the 80% share of 19. The remaining 20% is 3.8, and the two parts add back up to 19.

Discounts: 80% off an item priced $19 saves $15.2, so you pay $3.8.

Adding and taking away 80%

Increasing 19 by 80% gives 34.2 and decreasing it by 80% gives 3.8. These do not cancel out: raising 19 by 80% and then lowering the result by 80% ends at 6.84, because the second 80% is taken of a bigger number.
