What is this answer i am confused

the answer is 7 because you need to turn 5 and one fourth to uncommon denominator by multiplying 5 x 4 +1 which would be 21 so that equation would be 21 over 4 and because you are dividing you would need to flip the second part of the equation 3 fourths so it is also an uncommon denominator which would make it 4 thirds then the whole equation together would be 21 over 4 divided by four over 3, the you cancel out the 4 since they are diagnal from each other then the answer would then be 21 over 3, and 21 divided by 3 is 7
