How to work it out

  1. Turn the percentage into a decimal: 13 ÷ 100 = 0.13
  2. Multiply: 0.13 × 45 = 5.85
  3. Check: Work backwards: 5.85 ÷ 45 × 100 = 13%.

Another method. As a proportion of part to whole: 13/100 = part/45, so part = 13 × 45 ÷ 100 = 5.85. Both methods always give the same answer.

In a spreadsheet: =13%*45. 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

5.85 is the 13% share of 45. The remaining 87% is 39.15, and the two parts add back up to 45.

Discounts: 13% off an item priced $45 saves $5.85, so you pay $39.15.

Adding and taking away 13%

Increasing 45 by 13% gives 50.85 and decreasing it by 13% gives 39.15. These do not cancel out: raising 45 by 13% and then lowering the result by 13% ends at 44.2395, because the second 13% is taken of a bigger number.
