First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where is more likely to be overlooked.

I searched Google under the key words "math fractions" to get these possible sources:

http://www.aaamath.com/fra.html
http://www.coolmath4kids.com/fractions/
http://www.kidsolr.com/math/fractions.html
http://home.avvanta.com/~math/FDMENU.HTM
http://math.rice.edu/~lanius/fractions/index.html

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
