If you want the answers, I'll give you the sol'ns. That way, your teacher won't be curious on how'd you get it:

1.  \frac{1}{4} * 9 =   \frac{9}{4}  \\ 

2.  \frac{3}{4} * 12 =  9
3. 12 *  \frac{1}{4} = 3
4. 3 *  \frac{2}{3} = 2

Notice the numbers 2-4? I used cancellation because I wanted to keep the product in its lowest form.
