E) 4/3+1/5+2/7=
F) 1/2+2/3+1/4=
G) 3/4-1/2-7/5=

Answer 1

A) 3/5-2/3-1/2= (18-20-15)/30 = -17/30
B) 6/5-1/10+3/10=(12-1+3)/10 = 14/10 = 7/5
C) 1/2-3/4-4/3= (6-9-16)/12 = -19/12
D) 1/7-2/5= (5-14)/35 = -9/35
E) 4/3+1/5+2/7=(140+21+30)/105 = 191/105
F) 1/2+2/3+1/4= (6+8+3)/12 =17/12
G) 3/4-1/2-7/5= (15-10-28)/20 = -23/20
