Answer:


(21)/(4)

Explanation:

So to start, you need to make 3
(3)/(4\\) into an improper fraction, which will give you
(15)/(4). Then to make it easier, instead of dividing it by
(5)/(7), multiply it by the reciprocal (
(7)/(5) )

Your new expression should look like this:


(15)/(4) x
(7)/(5)

To make it even easier, you can simplify this expression even further. Looking at the numerators and denominators, we see that we have a 15 on top and a 5 on the bottom. Cross out the 5 and put a 1 in its place since 5 goes into 5 one time! Now we have to do it to the 15... Cross out the 15 and put a 3 since 5 goes into 15 three times!

Your simplified expression should look like this:


(3)/(4) x
(7)/(1)

Now, just multiply the numerators and the denominators to get your final answer of


(21)/(4)

Since you cannot simplify this anymore, that is your answer!!!
