How to work it out

  1. Turn the percentage into a decimal: 4 ÷ 100 = 0.04
  2. Multiply: 0.04 × 18 = 0.72
  3. Check: Work backwards: 0.72 ÷ 18 × 100 = 4%.

In a spreadsheet: =4%*18. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

Adding and taking away 4%
