Sample problems

  1. 4 2/3 + 4 1/3 = 9
  2. 3 2/6 + 3 1/6 = 6 1/2
  3. 4 2/5 − 1 3/5 = 2 4/5
  4. 3 1/4 − 1 2/4 = 1 3/4
  5. 5 2/5 + 2 4/5 = 8 1/5
  6. 5 2/3 + 2 1/3 = 8
  7. 5 1/4 + 2 3/4 = 8
  8. 5 2/5 − 5 1/5 = 1/5

These eight are one sample at medium difficulty — the generator makes a different set every time.

A worked example

4 2/3 + 4 1/3 = 9

  1. Add the wholes: 4 + 4 = 8
  2. Add the fractions: 2/3 + 1/3 = 3/3
  3. 3/3 is more than a whole: 3/3 = 1 0/3, so add 1 more whole
  4. Together: 9

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.
