How to work it out

  1. Turn the percentage into a decimal: 42 ÷ 100 = 0.42
  2. Multiply: 0.42 × 7 = 2.94
  3. Check: Work backwards: 2.94 ÷ 7 × 100 = 42%.

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

In a spreadsheet: =42%*7. 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 42% share of 7. The remaining 58% is 4.06, and the two parts add back up to 7.

Discounts: 42% off an item priced $7 saves $2.94, so you pay $4.06.

Adding and taking away 42%

Increasing 7 by 42% gives 9.94 and decreasing it by 42% gives 4.06. These do not cancel out: raising 7 by 42% and then lowering the result by 42% ends at 5.7652, because the second 42% is taken of a bigger number.
