How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 7 = 5.46
  3. Check: Work backwards: 5.46 ÷ 7 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/7, so part = 78 × 7 ÷ 100 = 5.46. Both methods always give the same answer.

In a spreadsheet: =78%*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

5.46 is the 78% share of 7. The remaining 22% is 1.54, and the two parts add back up to 7.

Discounts: 78% off an item priced $7 saves $5.46, so you pay $1.54.

Adding and taking away 78%

Increasing 7 by 78% gives 12.46 and decreasing it by 78% gives 1.54. These do not cancel out: raising 7 by 78% and then lowering the result by 78% ends at 2.7412, because the second 78% is taken of a bigger number.
