How to work it out

  1. Turn the percentage into a decimal: 40 ÷ 100 = 0.4
  2. Multiply: 0.4 × 99 = 39.6
  3. Check: Work backwards: 39.6 ÷ 99 × 100 = 40%.

In a spreadsheet: =40%*99. 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

39.6 is the 40% share of 99. The remaining 60% is 59.4, and the two parts add back up to 99.

Discounts: 40% off an item priced $99 saves $39.6, so you pay $59.4.

Adding and taking away 40%

Increasing 99 by 40% gives 138.6 and decreasing it by 40% gives 59.4. These do not cancel out: raising 99 by 40% and then lowering the result by 40% ends at 83.16, because the second 40% is taken of a bigger number.
