3. a) 23/15
b) -1/13
c)-55/18
d)-7/4
4. a) 6/13
b) 8
c) -16/31
d) -2/3
5. a= 2/3
b=-3/5
LHS
a+b = 2/3 + -3/5
=10/15 + -9/15
=10+-9/15
=10-9/15
=1/15
RHS
b+a = -3/5 + 2/3
=-9/15 + 10/15
=-9+10/15
=10-9/15
=1/15
As LHS=RHS, hence proved
6. a=5/12
b=1/2
c=7/12
LHS
(a+b)+c = (5/12+1/2)+7/12
=(5/12+6/12)+7/12
=(5+6/12)+7/12
=11/12+7/12
=11+7/12
=18/12
=3/2
RHS
a+(b+c) = 5/12+(1/2+7/12)
=5/12+(6/12+7/12)
=5/12+(6+7/12)
=5/12+13/12
=5+13/12
=18/12
=3/2
As LHS=RHS, hence proved.
