How to work it out

  1. Turn the percentage into a decimal: 29 ÷ 100 = 0.29
  2. Multiply: 0.29 × 42 = 12.18
  3. Check: Work backwards: 12.18 ÷ 42 × 100 = 29%.

Another method. As a proportion of part to whole: 29/100 = part/42, so part = 29 × 42 ÷ 100 = 12.18. Both methods always give the same answer.

In a spreadsheet: =29%*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

12.18 is the 29% share of 42. The remaining 71% is 29.82, and the two parts add back up to 42.

Discounts: 29% off an item priced $42 saves $12.18, so you pay $29.82.

Adding and taking away 29%

Increasing 42 by 29% gives 54.18 and decreasing it by 29% gives 29.82. These do not cancel out: raising 42 by 29% and then lowering the result by 29% ends at 38.4678, because the second 29% is taken of a bigger number.
