How to work it out

  1. Turn the percentage into a decimal: 9 ÷ 100 = 0.09
  2. Multiply: 0.09 × 79 = 7.11
  3. Check: Work backwards: 7.11 ÷ 79 × 100 = 9%.

Another method. As a proportion of part to whole: 9/100 = part/79, so part = 9 × 79 ÷ 100 = 7.11. Both methods always give the same answer.

In a spreadsheet: =9%*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

7.11 is the 9% share of 79. The remaining 91% is 71.89, and the two parts add back up to 79.

Discounts: 9% off an item priced $79 saves $7.11, so you pay $71.89.

Adding and taking away 9%

Increasing 79 by 9% gives 86.11 and decreasing it by 9% gives 71.89. These do not cancel out: raising 79 by 9% and then lowering the result by 9% ends at 78.3601, because the second 9% is taken of a bigger number.
