How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 12 = 9.36
  3. Check: Work backwards: 9.36 ÷ 12 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/12, so part = 78 × 12 ÷ 100 = 9.36. Both methods always give the same answer.

In a spreadsheet: =78%*12. 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

9.36 is the 78% share of 12. The remaining 22% is 2.64, and the two parts add back up to 12.

Discounts: 78% off an item priced $12 saves $9.36, so you pay $2.64.

Adding and taking away 78%

Increasing 12 by 78% gives 21.36 and decreasing it by 78% gives 2.64. These do not cancel out: raising 12 by 78% and then lowering the result by 78% ends at 4.6992, because the second 78% is taken of a bigger number.
