Answer:
Step-by-step explanation:
Given,
a = -11/27, b = 4/9 , c = -5/8
So,we first taken by L.H.S.
L.H.S. = a + ( b + c )
= -11/27 + [ 4/9 + ( -5/8 )]
= -11/27 + (4/9 - 5/8)
= -11/27 + ( 32 - 45 / 72 )
= -11/27 + ( -13/72 )
= -11/27 - 13/72
= -88 - 39 / 216
= -127 / 216
Now we taken by R.H.S.
R.H.S. = ( a + b ) + c
= [ (-11/27) + 4/9 ] + (-5/8)
= ( -11 + 12 /27) - 5/8
= 1/ 27 -5/8
= 8 - 135 / 216
= - 127 / 216
Hence L.H.S. = R.H.S.
Therefore , a + ( b + c ) = (a + b ) + c is verified.
