Answer 1

A) 2/5 + 3/7 =14/35 + 15/35= 29/35
B) 1/10 + 7/10 = 8/10 = 4/5
C) 1/6 + 5/12 + 1/4 = 2/12+5/12+3/12= 10/12 = 5/6
D) 27/36 - 4/6 = 27/36 - 24/36 = 3/36 = 1/12
E)1/5 - 2/25 = 5/25 - 2/25 = 3/25
F)5/28 - 3/28 = 2/28 = 1/14
G)8/13 -7/26 = 16/26 -7/26 = 9/26 
H)17/5 +1/15 = 51/15 + 1/15 = 52/15
