How to work it out

  1. Turn the percentage into a decimal: 9 ÷ 100 = 0.09
  2. Multiply: 0.09 × 77 = 6.93
  3. Check: Work backwards: 6.93 ÷ 77 × 100 = 9%.

Another method. As a proportion of part to whole: 9/100 = part/77, so part = 9 × 77 ÷ 100 = 6.93. Both methods always give the same answer.

In a spreadsheet: =9%*77. 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

6.93 is the 9% share of 77. The remaining 91% is 70.07, and the two parts add back up to 77.

Discounts: 9% off an item priced $77 saves $6.93, so you pay $70.07.

Adding and taking away 9%

Increasing 77 by 9% gives 83.93 and decreasing it by 9% gives 70.07. These do not cancel out: raising 77 by 9% and then lowering the result by 9% ends at 76.3763, because the second 9% is taken of a bigger number.
