How to work it out

  1. Turn the percentage into a decimal: 10 ÷ 100 = 0.1
  2. Multiply: 0.1 × 43 = 4.3
  3. Check: Work backwards: 4.3 ÷ 43 × 100 = 10%.

Another method. As a proportion of part to whole: 10/100 = part/43, so part = 10 × 43 ÷ 100 = 4.3. Both methods always give the same answer.

In a spreadsheet: =10%*43. 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

4.3 is the 10% share of 43. The remaining 90% is 38.7, and the two parts add back up to 43.

Discounts: 10% off an item priced $43 saves $4.3, so you pay $38.7.

Adding and taking away 10%

Increasing 43 by 10% gives 47.3 and decreasing it by 10% gives 38.7. These do not cancel out: raising 43 by 10% and then lowering the result by 10% ends at 42.57, because the second 10% is taken of a bigger number.
