How to work it out

  1. Turn the percentage into a decimal: 20 ÷ 100 = 0.2
  2. Multiply: 0.2 × 34 = 6.8
  3. Check: Work backwards: 6.8 ÷ 34 × 100 = 20%.

Another method. As a proportion of part to whole: 20/100 = part/34, so part = 20 × 34 ÷ 100 = 6.8. Both methods always give the same answer.

In a spreadsheet: =20%*34. 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

6.8 is the 20% share of 34. The remaining 80% is 27.2, and the two parts add back up to 34.

Discounts: 20% off an item priced $34 saves $6.8, so you pay $27.2.

Adding and taking away 20%

Increasing 34 by 20% gives 40.8 and decreasing it by 20% gives 27.2. These do not cancel out: raising 34 by 20% and then lowering the result by 20% ends at 32.64, because the second 20% is taken of a bigger number.
