How to work it out

  1. Turn the percentage into a decimal: 20 ÷ 100 = 0.2
  2. Multiply: 0.2 × 28 = 5.6
  3. Check: Work backwards: 5.6 ÷ 28 × 100 = 20%.

Another method. As a proportion of part to whole: 20/100 = part/28, so part = 20 × 28 ÷ 100 = 5.6. Both methods always give the same answer.

In a spreadsheet: =20%*28. 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

5.6 is the 20% share of 28. The remaining 80% is 22.4, and the two parts add back up to 28.

Discounts: 20% off an item priced $28 saves $5.6, so you pay $22.4.

Adding and taking away 20%

Increasing 28 by 20% gives 33.6 and decreasing it by 20% gives 22.4. These do not cancel out: raising 28 by 20% and then lowering the result by 20% ends at 26.88, because the second 20% is taken of a bigger number.
