3 3/4 + 1 1/4 + 2 2/4
3/4 + 1/4 + 2/4 = 1 1/2
3 + 1 + 2 + 1 1/2 = 7 1/2 cups total
-2 and+2 =0
1/2 -3/2= -2/2 or -1
7-1=6

Although you do not give the rates I assume the answer is D as it is the only positive multiplication. You cannot have negative height.
![\frac{ 3^{4} }{ 3^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%203%5E%7B4%7D%20%7D%7B%203%5E%7B2%7D%20%7D%20)
First, take about the
![3^{4}](https://tex.z-dn.net/?f=%203%5E%7B4%7D)
and
![3^{2}](https://tex.z-dn.net/?f=%203%5E%7B2%7D%20)
![\frac{3 x 3 x 3 x 3}{3 x 3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%20x%203%20x%203%20x%203%7D%7B3%20x%203%7D%20)
You can cancel out the two 3's on the bottom using two of the threes from the numerator
