How to work it out

  1. Turn the percentage into a decimal: 70 ÷ 100 = 0.7
  2. Multiply: 0.7 × 27 = 18.9
  3. Check: Work backwards: 18.9 ÷ 27 × 100 = 70%.

Another method. As a proportion of part to whole: 70/100 = part/27, so part = 70 × 27 ÷ 100 = 18.9. Both methods always give the same answer.

In a spreadsheet: =70%*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

18.9 is the 70% share of 27. The remaining 30% is 8.1, and the two parts add back up to 27.

Discounts: 70% off an item priced $27 saves $18.9, so you pay $8.1.

Adding and taking away 70%

Increasing 27 by 70% gives 45.9 and decreasing it by 70% gives 8.1. These do not cancel out: raising 27 by 70% and then lowering the result by 70% ends at 13.77, because the second 70% is taken of a bigger number.
