How to work it out

  1. Turn the percentage into a decimal: 23 ÷ 100 = 0.23
  2. Multiply: 0.23 × 42 = 9.66
  3. Check: Work backwards: 9.66 ÷ 42 × 100 = 23%.

Another method. As a proportion of part to whole: 23/100 = part/42, so part = 23 × 42 ÷ 100 = 9.66. Both methods always give the same answer.

In a spreadsheet: =23%*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

9.66 is the 23% share of 42. The remaining 77% is 32.34, and the two parts add back up to 42.

Discounts: 23% off an item priced $42 saves $9.66, so you pay $32.34.

Adding and taking away 23%

Increasing 42 by 23% gives 51.66 and decreasing it by 23% gives 32.34. These do not cancel out: raising 42 by 23% and then lowering the result by 23% ends at 39.7782, because the second 23% is taken of a bigger number.
