Answer:
a+(b+c)=(a+b)+c = -13/54 verified
Step-by-step explanation:
a = -11/27, b = 4/9 and c = -5/18
consider a+(b+c)
-11/27 +( 4/9 +-5/18)
=-11/27 +( 4*2 -5*1/18)
=-11/27+{(8-5)/18}
-11/27+3/18
=-11*2+3*3/54
=-22+9/54
=-13/54
Now take(a+b)+c
=(-11/27 +4/9) -5/18
=(-11*1+4*3/27)-5/18
=(-11+12/27)-5/18
=1/27-5/18
=1*2-5*3/54
=2-15/54
=-13/54
LHS = RHS
a+(b+c)=(a+b)+c = -13/54 verified
