How to work it out

  1. Turn the percentage into a decimal: 79 ÷ 100 = 0.79
  2. Multiply: 0.79 × 9 = 7.11
  3. Check: Work backwards: 7.11 ÷ 9 × 100 = 79%.

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

In a spreadsheet: =79%*9. 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 79% share of 9. The remaining 21% is 1.89, and the two parts add back up to 9.

Discounts: 79% off an item priced $9 saves $7.11, so you pay $1.89.

Adding and taking away 79%

Increasing 9 by 79% gives 16.11 and decreasing it by 79% gives 1.89. These do not cancel out: raising 9 by 79% and then lowering the result by 79% ends at 3.3831, because the second 79% is taken of a bigger number.
