How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 3 = 2.34
  3. Check: Work backwards: 2.34 ÷ 3 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/3, so part = 78 × 3 ÷ 100 = 2.34. Both methods always give the same answer.

In a spreadsheet: =78%*3. 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

2.34 is the 78% share of 3. The remaining 22% is 0.66, and the two parts add back up to 3.

Discounts: 78% off an item priced $3 saves $2.34, so you pay $0.66.

Adding and taking away 78%

Increasing 3 by 78% gives 5.34 and decreasing it by 78% gives 0.66. These do not cancel out: raising 3 by 78% and then lowering the result by 78% ends at 1.1748, because the second 78% is taken of a bigger number.
