Question

if (a+b)+c=a+(b+c) then verify this...If a = -7/11, b= 2/-5, c=-13/22

Answer 1

Hello Mate!

( a + b ) + c = a + ( b + c )

Note : Here assosiative property is used.

( - 7/11 - 2/5 ) - 13/22 = -7/11 - ( 2/5 + 13/22 )
( - 70/110 - 44/110 ) - 65/110 = -70/110 - ( 44/110 + 65/110 )

- 114/110 - 65/110 = -70/110 - 109/110

-179/110 = -179/110

LHS = RHS

Hope it helps☺!
