First you have to change your fractions to have the same denominator which in this case will be 20. That makes the question read 7 5/20 - 5 12/20 =. Now you still have a problem because we need to subtract 12 from 5. So let us change the whole number 7 to 6 and add 20/20 to the 5/20 to get 6 25/20 - 5 12/20 = 1 13/20. That is your answer, no need to simplify. Good luck in your studies. God Bless.

First you have to convert the 7 1/4 and 5 3/5
7 1/4 = 29/4
5 3/5 = 28/5
Find a common denominator, which in this case would be 20.
29/4=145/20
28/5=112/20
145/20 - 112/20 = 33/20 or 1 13/20

7 1/4= 29/4 and 5 3/5=28/5
29/4 -> 145/20 and 28/5 -> 112/20
145/20-112/20=33/20 or:
1 13/20
