Answer:
3
Step-by-step explanation:
You use a method called KCF (Keep, change, flip), which means that you keep the first fraction, change the division sign to a multiplication sign, and flip the fraction of 3/4 to 4/3. After that you can just multiply [tex]\frac{9}{4}[/tex] into [tex]\frac{4}{3\\}[/tex] which gives you [tex]\frac{36}{12}[/tex] and can be simplified to give you 3.
