Question

1)Verify associativity of addition of rational numbers i.e.,(x+y)+z=x+(y+z),when:x=1/2,y =2/3,z=(-1/5)

Answer 1

Answer:

LHS is not equal to RHS

Hence, verified

Step-by-step explanation:

LHS- (1/2+2/3)+ (-1/5)

     = (5/6-1/5)

     = (25-6)/30

     = 19/30

RHS- 1/2 + [2/3+(-1/5)]

      = 1/2 + [7/15]

      = [15+14]/30

      = 29/30
