Answer:
(-3/2+5/7)+4/5=3/2+(5/7+4/5)
LET. a= -3/2
b= 5/7
c= 4/5
HERE (a+b)+c=a+(b+c)
This pattern is called associative property of addition
LHS
(-3/2+5/7)+4/5
(-21+10/14)+4/5 (lcm of 7&2=14)
(-11/14)+4/5
-55+56/70 (lcm of 14&5)
1/70
RHS
-3/2+(5/7+4/5)
-3/2+(25+28/35) (lcm of 7&5)
-3/2+53/35
-105+106/70 (lcm of 35&2)
1/70
LHS=1/70 RHS=1/70
1/70=1/70
LHS=RHS
