How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 25 = 19.5
  3. Check: Work backwards: 19.5 ÷ 25 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/25, so part = 78 × 25 ÷ 100 = 19.5. Both methods always give the same answer.

In a spreadsheet: =78%*25. 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

19.5 is the 78% share of 25. The remaining 22% is 5.5, and the two parts add back up to 25.

Discounts: 78% off an item priced $25 saves $19.5, so you pay $5.5.

Adding and taking away 78%

Increasing 25 by 78% gives 44.5 and decreasing it by 78% gives 5.5. These do not cancel out: raising 25 by 78% and then lowering the result by 78% ends at 9.79, because the second 78% is taken of a bigger number.
