A worked example

2/4 + 5/6 = 4/3

  1. Common denominator for 4 and 6: 12
  2. 2/4 = 6/12 (multiply top and bottom by 3)
  3. 5/6 = 10/12 (multiply top and bottom by 2)
  4. Add the numerators: 6 + 10 = 16, so 16/12
  5. Divide top and bottom by 4: 4/3

About these worksheets

Fractions and decimals are where a small slip in one step changes the whole answer, so the worked steps matter. Every sheet is generated fresh, so you can print a new one on the same skill as often as you need — different numbers, same difficulty.

Pick how many problems you want and whether they should be easy, medium or hard, then download a PDF with a matching answer key. The key can show the worked steps for every problem, which is what a parent needs to see where a wrong answer went wrong.
