How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 45 = 29.7
  3. Check: Work backwards: 29.7 ÷ 45 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/45, so part = 66 × 45 ÷ 100 = 29.7. Both methods always give the same answer.

In a spreadsheet: =66%*45. 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

29.7 is the 66% share of 45. The remaining 34% is 15.3, and the two parts add back up to 45.

Discounts: 66% off an item priced $45 saves $29.7, so you pay $15.3.

Adding and taking away 66%

Increasing 45 by 66% gives 74.7 and decreasing it by 66% gives 15.3. These do not cancel out: raising 45 by 66% and then lowering the result by 66% ends at 25.398, because the second 66% is taken of a bigger number.
