How to work it out

  1. Turn the percentage into a decimal: 1 ÷ 100 = 0.01
  2. Multiply: 0.01 × 78 = 0.78
  3. Check: Work backwards: 0.78 ÷ 78 × 100 = 1%.

Another method. As a proportion of part to whole: 1/100 = part/78, so part = 1 × 78 ÷ 100 = 0.78. Both methods always give the same answer.

In a spreadsheet: =1%*78. 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

0.78 is the 1% share of 78. The remaining 99% is 77.22, and the two parts add back up to 78.

Discounts: 1% off an item priced $78 saves $0.78, so you pay $77.22.

Adding and taking away 1%

Increasing 78 by 1% gives 78.78 and decreasing it by 1% gives 77.22. These do not cancel out: raising 78 by 1% and then lowering the result by 1% ends at 77.9922, because the second 1% is taken of a bigger number.
