How to work it out

  1. Turn the percentage into a decimal: 64 ÷ 100 = 0.64
  2. Multiply: 0.64 × 78 = 49.92
  3. Check: Work backwards: 49.92 ÷ 78 × 100 = 64%.

Another method. As a proportion of part to whole: 64/100 = part/78, so part = 64 × 78 ÷ 100 = 49.92. Both methods always give the same answer.

In a spreadsheet: =64%*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

49.92 is the 64% share of 78. The remaining 36% is 28.08, and the two parts add back up to 78.

Discounts: 64% off an item priced $78 saves $49.92, so you pay $28.08.

Adding and taking away 64%

Increasing 78 by 64% gives 127.92 and decreasing it by 64% gives 28.08. These do not cancel out: raising 78 by 64% and then lowering the result by 64% ends at 46.0512, because the second 64% is taken of a bigger number.
