How to work it out

  1. Turn the percentage into a decimal: 42 ÷ 100 = 0.42
  2. Multiply: 0.42 × 42 = 17.64
  3. Check: Work backwards: 17.64 ÷ 42 × 100 = 42%.

Another method. As a proportion of part to whole: 42/100 = part/42, so part = 42 × 42 ÷ 100 = 17.64. Both methods always give the same answer.

In a spreadsheet: =42%*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

17.64 is the 42% share of 42. The remaining 58% is 24.36, and the two parts add back up to 42.

Discounts: 42% off an item priced $42 saves $17.64, so you pay $24.36.

Adding and taking away 42%

Increasing 42 by 42% gives 59.64 and decreasing it by 42% gives 24.36. These do not cancel out: raising 42 by 42% and then lowering the result by 42% ends at 34.5912, because the second 42% is taken of a bigger number.
