How to work it out

  1. Turn the percentage into a decimal: 2 ÷ 100 = 0.02
  2. Multiply: 0.02 × 42 = 0.84
  3. Check: Work backwards: 0.84 ÷ 42 × 100 = 2%.

Another method. As a proportion of part to whole: 2/100 = part/42, so part = 2 × 42 ÷ 100 = 0.84. Both methods always give the same answer.

In a spreadsheet: =2%*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

0.84 is the 2% share of 42. The remaining 98% is 41.16, and the two parts add back up to 42.

Discounts: 2% off an item priced $42 saves $0.84, so you pay $41.16.

Adding and taking away 2%

Increasing 42 by 2% gives 42.84 and decreasing it by 2% gives 41.16. These do not cancel out: raising 42 by 2% and then lowering the result by 2% ends at 41.9832, because the second 2% is taken of a bigger number.
