Question

given three rational number vertify the assocative under addition 3/4,-1/2,2/3

Answer 1

Let, a=3/4
b=-1/2
c=2/3
To verify: a+(b+c)=(a+b)+c
L.H.S: a+(b+c)
=3/4 + (-1/2 + 2/3)
=3/4 + -1/6
= 7/12
L.H.S= -5/12
R.H.S=(a+b)+c
=(3/4 + -1/2) + 2/3
=1/4 + 2/3
=7/12
R.H.S=7/12
Clearly,
7/12=7/12
Therefore, 
Associative property holds good under addition.
