How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 27 = 21.06
  3. Check: Work backwards: 21.06 ÷ 27 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/27, so part = 78 × 27 ÷ 100 = 21.06. Both methods always give the same answer.

In a spreadsheet: =78%*27. 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

21.06 is the 78% share of 27. The remaining 22% is 5.94, and the two parts add back up to 27.

Discounts: 78% off an item priced $27 saves $21.06, so you pay $5.94.

Adding and taking away 78%

Increasing 27 by 78% gives 48.06 and decreasing it by 78% gives 5.94. These do not cancel out: raising 27 by 78% and then lowering the result by 78% ends at 10.5732, because the second 78% is taken of a bigger number.
