How to work it out

  1. Turn the percentage into a decimal: 40 ÷ 100 = 0.4
  2. Multiply: 0.4 × 16 = 6.4
  3. Check: Work backwards: 6.4 ÷ 16 × 100 = 40%.

Another method. As a proportion of part to whole: 40/100 = part/16, so part = 40 × 16 ÷ 100 = 6.4. Both methods always give the same answer.

In a spreadsheet: =40%*16. 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

6.4 is the 40% share of 16. The remaining 60% is 9.6, and the two parts add back up to 16.

Discounts: 40% off an item priced $16 saves $6.4, so you pay $9.6.

Adding and taking away 40%

Increasing 16 by 40% gives 22.4 and decreasing it by 40% gives 9.6. These do not cancel out: raising 16 by 40% and then lowering the result by 40% ends at 13.44, because the second 40% is taken of a bigger number.
