How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 10 = 6.6
  3. Check: Work backwards: 6.6 ÷ 10 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/10, so part = 66 × 10 ÷ 100 = 6.6. Both methods always give the same answer.

In a spreadsheet: =66%*10. 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

6.6 is the 66% share of 10. The remaining 34% is 3.4, and the two parts add back up to 10.

Discounts: 66% off an item priced $10 saves $6.6, so you pay $3.4.

Adding and taking away 66%

Increasing 10 by 66% gives 16.6 and decreasing it by 66% gives 3.4. These do not cancel out: raising 10 by 66% and then lowering the result by 66% ends at 5.644, because the second 66% is taken of a bigger number.
