How to work it out

  1. Turn the percentage into a decimal: 1 ÷ 100 = 0.01
  2. Multiply: 0.01 × 77 = 0.77
  3. Check: Work backwards: 0.77 ÷ 77 × 100 = 1%.

Another method. As a proportion of part to whole: 1/100 = part/77, so part = 1 × 77 ÷ 100 = 0.77. Both methods always give the same answer.

In a spreadsheet: =1%*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

0.77 is the 1% share of 77. The remaining 99% is 76.23, and the two parts add back up to 77.

Discounts: 1% off an item priced $77 saves $0.77, so you pay $76.23.

Adding and taking away 1%

Increasing 77 by 1% gives 77.77 and decreasing it by 1% gives 76.23. These do not cancel out: raising 77 by 1% and then lowering the result by 1% ends at 76.9923, because the second 1% is taken of a bigger number.
