How to work it out

  1. Turn the percentage into a decimal: 45 ÷ 100 = 0.45
  2. Multiply: 0.45 × 64 = 28.8
  3. Check: Work backwards: 28.8 ÷ 64 × 100 = 45%.

Another method. As a proportion of part to whole: 45/100 = part/64, so part = 45 × 64 ÷ 100 = 28.8. Both methods always give the same answer.

In a spreadsheet: =45%*64. 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

28.8 is the 45% share of 64. The remaining 55% is 35.2, and the two parts add back up to 64.

Discounts: 45% off an item priced $64 saves $28.8, so you pay $35.2.

Adding and taking away 45%

Increasing 64 by 45% gives 92.8 and decreasing it by 45% gives 35.2. These do not cancel out: raising 64 by 45% and then lowering the result by 45% ends at 51.04, because the second 45% is taken of a bigger number.
