How to work it out

  1. Turn the percentage into a decimal: 5 ÷ 100 = 0.05
  2. Multiply: 0.05 × 77 = 3.85
  3. Check: Work backwards: 3.85 ÷ 77 × 100 = 5%.

Another method. As a proportion of part to whole: 5/100 = part/77, so part = 5 × 77 ÷ 100 = 3.85. Both methods always give the same answer.

In a spreadsheet: =5%*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

3.85 is the 5% share of 77. The remaining 95% is 73.15, and the two parts add back up to 77.

Discounts: 5% off an item priced $77 saves $3.85, so you pay $73.15.

Adding and taking away 5%

Increasing 77 by 5% gives 80.85 and decreasing it by 5% gives 73.15. These do not cancel out: raising 77 by 5% and then lowering the result by 5% ends at 76.8075, because the second 5% is taken of a bigger number.
