How to work it out

  1. Turn the percentage into a decimal: 4 ÷ 100 = 0.04
  2. Multiply: 0.04 × 91 = 3.64
  3. Check: Work backwards: 3.64 ÷ 91 × 100 = 4%.

Another method. As a proportion of part to whole: 4/100 = part/91, so part = 4 × 91 ÷ 100 = 3.64. Both methods always give the same answer.

In a spreadsheet: =4%*91. 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

3.64 is the 4% share of 91. The remaining 96% is 87.36, and the two parts add back up to 91.

Discounts: 4% off an item priced $91 saves $3.64, so you pay $87.36.

Adding and taking away 4%

Increasing 91 by 4% gives 94.64 and decreasing it by 4% gives 87.36. These do not cancel out: raising 91 by 4% and then lowering the result by 4% ends at 90.8544, because the second 4% is taken of a bigger number.
