How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 84 = 55.44
  3. Check: Work backwards: 55.44 ÷ 84 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/84, so part = 66 × 84 ÷ 100 = 55.44. Both methods always give the same answer.

In a spreadsheet: =66%*84. 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

55.44 is the 66% share of 84. The remaining 34% is 28.56, and the two parts add back up to 84.

Discounts: 66% off an item priced $84 saves $55.44, so you pay $28.56.

Adding and taking away 66%

Increasing 84 by 66% gives 139.44 and decreasing it by 66% gives 28.56. These do not cancel out: raising 84 by 66% and then lowering the result by 66% ends at 47.4096, because the second 66% is taken of a bigger number.
