Question

if a= -4/9 ,b = 7/3 and c = 11/6 , show that a - b -c ≠ a - (b-c)​

Answer 1

Ist Method --->

Given: a=-4/9, b=7/3, c=11/6

LHS = a-b-c

= -4/9 - 7/3 - 11/6

= (-8 - 42 - 33) / 18

= -83/18

RHS = a -(b-c)

= -4/9 - (7/3 - 11/6)

= -4/9 - (1/2)

=-4/9 - 1/2

=-17/18

Here, LHS not equal to RHS.

IInd Method--->

RHS = a-(b-c)

= a-b+c [- & - will join to

form + ]

Here, LHS is not equal to RHS.

Hope its clear for you.
