How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 4 = 2.64
  3. Check: Work backwards: 2.64 ÷ 4 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/4, so part = 66 × 4 ÷ 100 = 2.64. Both methods always give the same answer.

In a spreadsheet: =66%*4. 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

2.64 is the 66% share of 4. The remaining 34% is 1.36, and the two parts add back up to 4.

Discounts: 66% off an item priced $4 saves $2.64, so you pay $1.36.

Adding and taking away 66%

Increasing 4 by 66% gives 6.64 and decreasing it by 66% gives 1.36. These do not cancel out: raising 4 by 66% and then lowering the result by 66% ends at 2.2576, because the second 66% is taken of a bigger number.
