How to work it out

  1. Turn the percentage into a decimal: 65 ÷ 100 = 0.65
  2. Multiply: 0.65 × 1 = 0.65
  3. Check: Work backwards: 0.65 ÷ 1 × 100 = 65%.

Another method. As a proportion of part to whole: 65/100 = part/1, so part = 65 × 1 ÷ 100 = 0.65. Both methods always give the same answer.

In a spreadsheet: =65%*1. 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

0.65 is the 65% share of 1. The remaining 35% is 0.35, and the two parts add back up to 1.

Discounts: 65% off an item priced $1 saves $0.65, so you pay $0.35.

Adding and taking away 65%

Increasing 1 by 65% gives 1.65 and decreasing it by 65% gives 0.35. These do not cancel out: raising 1 by 65% and then lowering the result by 65% ends at 0.5775, because the second 65% is taken of a bigger number.
