step 1
Find the sum of 37/8 and 11/4
37/8+11/4
Remember that
11/4=(2/2)(11/4)=22/8
so
37/8+22/8=59/8
step 2
Find the difference
37/8-22/8=15/8
step 3
Divide the sum by the difference
so
59/8 : 15/8=59/15
therefore
the answer is 59/15
step 4
Convert to mixed number
59/15=45/15+14/15=3+14/15=3 14/15
the mixed number is 3 14/15
