Question

if a=-11/27 b=4/9 and c=-5/18 then verify that a+(b+c) = (a+b)+c
​

Answer 1

Answer:

L. H. S=a+(b+c)

=11/27+(4/9+5/18)

=11/27 + 8+5/18

=11/27 + 13/18

=22+39/54

=61/54

=1whole7/54

R. H. S=(a+b)+c

=(11/27+4/9)+5/18

=23/27+5/18

=46/54+15/54

=61/54

=1 whole 7/54

Therefore, L. H. S=R.H.S,hence verified

Answer 2

L. H. S=a+(b+c)

=11/27+(4/9+5/18)

=11/27 + 8+5/18

=11/27 + 13/18

=22+39/54

=61/54

=1 whole 7/54

R. H. S=(a+b)+c

=(11/27+4/9)+5/18

=23/27+5/18

=46/54+15/54

=61/54

=1 whole 7/54

Therefore, L. H. S=R.H.S,hence verified
