How to work it out
- Turn the percentage into a decimal: 4 ÷ 100 = 0.04
- Multiply: 0.04 × 42 = 1.68
- Check: Work backwards: 1.68 ÷ 42 × 100 = 4%.
Another method. As a proportion of part to whole: 4/100 = part/42, so part = 4 × 42 ÷ 100 = 1.68. Both methods always give the same answer.
In a spreadsheet: =4%*42. 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
1.68 is the 4% share of 42. The remaining 96% is 40.32, and the two parts add back up to 42.

Adding and taking away 4%
Increasing 42 by 4% gives 43.68 and decreasing it by 4% gives 40.32. These do not cancel out: raising 42 by 4% and then lowering the result by 4% ends at 41.9328, because the second 4% is taken of a bigger number.
