How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 64 = 42.24
  3. Check: Work backwards: 42.24 ÷ 64 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/64, so part = 66 × 64 ÷ 100 = 42.24. Both methods always give the same answer.

In a spreadsheet: =66%*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

42.24 is the 66% share of 64. The remaining 34% is 21.76, and the two parts add back up to 64.

Discounts: 66% off an item priced $64 saves $42.24, so you pay $21.76.

Adding and taking away 66%

Increasing 64 by 66% gives 106.24 and decreasing it by 66% gives 21.76. These do not cancel out: raising 64 by 66% and then lowering the result by 66% ends at 36.1216, because the second 66% is taken of a bigger number.
