(12/15) / (3/five) - ANS-1 1/3
12 x five = 60
15 x 3 = forty five
60/forty five = four/three
4/three = 1 1/three
1/2 + 4/five - ANS-1 3/10
1*5/2*five + 4*2/5*2 = five/10 + eight/10 = 13/10 = 1 three/10
thirteen goes into 10 one time.
13-10 = 3
there are 3 left over
consequently the combined fraction might be 1 three/10

four/five + 6/7 - ANS-1 23/35
4*7/5*7 + 6*five/7*5 = 28/35+ 30/35 = fifty eight/35
fifty eight is going into 35 one time
58-35 = 23
there are 23 left over
consequently mixed fraction could be 1 23/35
