How to work it out

  1. Turn the percentage into a decimal: 43 ÷ 100 = 0.43
  2. Multiply: 0.43 × 100 = 43
  3. Check: Work backwards: 43 ÷ 100 × 100 = 43%.

Another method. As a proportion of part to whole: 43/100 = part/100, so part = 43 × 100 ÷ 100 = 43. Both methods always give the same answer.

In a spreadsheet: =43%*100. 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

43 is the 43% share of 100. The remaining 57% is 57, and the two parts add back up to 100.

Discounts: 43% off an item priced $100 saves $43, so you pay $57.

Adding and taking away 43%

Increasing 100 by 43% gives 143 and decreasing it by 43% gives 57. These do not cancel out: raising 100 by 43% and then lowering the result by 43% ends at 81.51, because the second 43% is taken of a bigger number.
