Multiplying Fractions!
If you don't yet know what fractions are, then you should probably learn more about them first. Try this great site! Fractions
You know how to add and subtract fractions, but now it's time to learn how to multiply them! You would probably think it would be harder, right? Wrong! When you add or subtract, the denominators have to be equal. Example:
The denominators have to be equal. This is not the case in multiplication. In multiplication, you multiply straight across, like this:
First, multiply the 3 and the 7. That gives you 21, so 21 is your answer for the numerator. Then, you multiply 4 and 11, which gives you the answer for the denominator. Now you try!
5/7 x 1/2=?
If you said 5/14, you were right! You probably multiplied 5x1 and then 7x14, right? Ok, let's try another one.
10/13 x4/5
Did you say 40/65? You multiplied the 10x4 and 13x5. If you did you were partly right, but you still needed to simplify it.
You know, multiplying the numbers is only part of the work. If you get a number that can be simplified, you need to simplify them! But I'm not the expert on that. Try this page all about them! Simplifying Fractions
If you think you've got it down, go to:

It's great practice.
Also, you should visist this wiki about Dividing Fractions. Good luck!

Like everyone else says, you should put more pics/examples. You should also link your website to other wiki pages. For example, some people who are new to fractions might not know what they are. You can link the word "fractions" to a wiki page about fractions, so whoever's reading can just go to that page to learn about it.

More examples would be helpful. Good internal links, but links out to more practice and information would also be helpful.
