Question

For x = -2/3 , y = 5/9 , z = -7/6 , find the values of ( x – y) – z and x – ( y – z ). Are they equal?​

Answer 1

Answer:

Value is 43/18 and 18/9

Step-by-step explanation:

x= -2/3

y=5/9

z= -7/6

So , (x - y) - z and x - ( y - z )

= ( -2/3 - 5/9 ) - ( -7/6 ) and -2/3 - ( 5/9 - (-7/9 )

= 11/9+7/6 and -2/3 - 12/9

= 43/18 and 18/9

So, they are not equal.
