How to work it out

  1. Turn the percentage into a decimal: 49 ÷ 100 = 0.49
  2. Multiply: 0.49 × 40 = 19.6
  3. Check: Work backwards: 19.6 ÷ 40 × 100 = 49%.

Another method. As a proportion of part to whole: 49/100 = part/40, so part = 49 × 40 ÷ 100 = 19.6. Both methods always give the same answer.

In a spreadsheet: =49%*40. 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

19.6 is the 49% share of 40. The remaining 51% is 20.4, and the two parts add back up to 40.

Discounts: 49% off an item priced $40 saves $19.6, so you pay $20.4.

Adding and taking away 49%

Increasing 40 by 49% gives 59.6 and decreasing it by 49% gives 20.4. These do not cancel out: raising 40 by 49% and then lowering the result by 49% ends at 30.396, because the second 49% is taken of a bigger number.
