2. 8 11/20

Step-by-step explanation:

1. 2/5 + 45/7 ( mixed fraction to improper fraction) - 8/3 (mixed to improper) =

Find the LCD of 5, 7, 3 = 105 then solve (105/5*2= 42) + (105/7*45=675) - 105/3*8=280)

42+675-280/105 =437/105 or 4 17/105

2. 4/5 + 15/2 - 7/4 (mixed to improper fraction)

Find the LCD of 5,2,4= 20 then solve

56+150-35/20 =171/20 or 8 11/20
