How to work it out

  1. Turn the percentage into a decimal: 20 ÷ 100 = 0.2
  2. Multiply: 0.2 × 79 = 15.8
  3. Check: Work backwards: 15.8 ÷ 79 × 100 = 20%.

Another method. As a proportion of part to whole: 20/100 = part/79, so part = 20 × 79 ÷ 100 = 15.8. Both methods always give the same answer.

In a spreadsheet: =20%*79. 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

15.8 is the 20% share of 79. The remaining 80% is 63.2, and the two parts add back up to 79.

Discounts: 20% off an item priced $79 saves $15.8, so you pay $63.2.

Adding and taking away 20%

Increasing 79 by 20% gives 94.8 and decreasing it by 20% gives 63.2. These do not cancel out: raising 79 by 20% and then lowering the result by 20% ends at 75.84, because the second 20% is taken of a bigger number.
