How to work it out

  1. Turn the percentage into a decimal: 19 ÷ 100 = 0.19
  2. Multiply: 0.19 × 42 = 7.98
  3. Check: Work backwards: 7.98 ÷ 42 × 100 = 19%.

Another method. As a proportion of part to whole: 19/100 = part/42, so part = 19 × 42 ÷ 100 = 7.98. Both methods always give the same answer.

In a spreadsheet: =19%*42. 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

7.98 is the 19% share of 42. The remaining 81% is 34.02, and the two parts add back up to 42.

Discounts: 19% off an item priced $42 saves $7.98, so you pay $34.02.

Adding and taking away 19%

Increasing 42 by 19% gives 49.98 and decreasing it by 19% gives 34.02. These do not cancel out: raising 42 by 19% and then lowering the result by 19% ends at 40.4838, because the second 19% is taken of a bigger number.
