  2. Keep the denominator: 12/5
  3. 5 goes into 12 2 times with 2 left: 2 2/5

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.
