Answer:
4 5/8 the answer you have is correct :)
Explanation:
First, you want to make the mixed fraction into an improper fraction.
7 x 4 + 3 = 31 (31/4)
3 x 8 + 1 = 25 (25/8)
Now you want them both to have a common denominator.
31/4 x 2/2 = 62/8
Now you are ready to subtract!
62/8 - 25/8 = 37/8
Finally, convert 37/8 to a proper fraction.
37/8 = 4 5/8
