How to work it out

  1. Turn the percentage into a decimal: 47 ÷ 100 = 0.47
  2. Multiply: 0.47 × 42 = 19.74
  3. Check: Work backwards: 19.74 ÷ 42 × 100 = 47%.

Another method. As a proportion of part to whole: 47/100 = part/42, so part = 47 × 42 ÷ 100 = 19.74. Both methods always give the same answer.

In a spreadsheet: =47%*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

19.74 is the 47% share of 42. The remaining 53% is 22.26, and the two parts add back up to 42.

Discounts: 47% off an item priced $42 saves $19.74, so you pay $22.26.

Adding and taking away 47%

Increasing 42 by 47% gives 61.74 and decreasing it by 47% gives 22.26. These do not cancel out: raising 42 by 47% and then lowering the result by 47% ends at 32.7222, because the second 47% is taken of a bigger number.
