How to work it out

  1. Turn the percentage into a decimal: 64 ÷ 100 = 0.64
  2. Multiply: 0.64 × 85 = 54.4
  3. Check: Work backwards: 54.4 ÷ 85 × 100 = 64%.

Another method. As a proportion of part to whole: 64/100 = part/85, so part = 64 × 85 ÷ 100 = 54.4. Both methods always give the same answer.

In a spreadsheet: =64%*85. 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

54.4 is the 64% share of 85. The remaining 36% is 30.6, and the two parts add back up to 85.

Discounts: 64% off an item priced $85 saves $54.4, so you pay $30.6.

Adding and taking away 64%

Increasing 85 by 64% gives 139.4 and decreasing it by 64% gives 30.6. These do not cancel out: raising 85 by 64% and then lowering the result by 64% ends at 50.184, because the second 64% is taken of a bigger number.
