How to work it out

  1. Turn the percentage into a decimal: 7 ÷ 100 = 0.07
  2. Multiply: 0.07 × 42 = 2.94
  3. Check: Work backwards: 2.94 ÷ 42 × 100 = 7%.

Another method. As a proportion of part to whole: 7/100 = part/42, so part = 7 × 42 ÷ 100 = 2.94. Both methods always give the same answer.

In a spreadsheet: =7%*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

2.94 is the 7% share of 42. The remaining 93% is 39.06, and the two parts add back up to 42.

Discounts: 7% off an item priced $42 saves $2.94, so you pay $39.06.

Adding and taking away 7%

Increasing 42 by 7% gives 44.94 and decreasing it by 7% gives 39.06. These do not cancel out: raising 42 by 7% and then lowering the result by 7% ends at 41.7942, because the second 7% is taken of a bigger number.
