How to work it out

  1. Turn the percentage into a decimal: 13 ÷ 100 = 0.13
  2. Multiply: 0.13 × 78 = 10.14
  3. Check: Work backwards: 10.14 ÷ 78 × 100 = 13%.

Another method. As a proportion of part to whole: 13/100 = part/78, so part = 13 × 78 ÷ 100 = 10.14. Both methods always give the same answer.

In a spreadsheet: =13%*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

10.14 is the 13% share of 78. The remaining 87% is 67.86, and the two parts add back up to 78.

Discounts: 13% off an item priced $78 saves $10.14, so you pay $67.86.

Adding and taking away 13%

Increasing 78 by 13% gives 88.14 and decreasing it by 13% gives 67.86. These do not cancel out: raising 78 by 13% and then lowering the result by 13% ends at 76.6818, because the second 13% is taken of a bigger number.
