Question

(X+y)+z=x+(y+z)
If....x=1/2 ; y=2/3 ; z=-1/5

Answer 1

Step-by-step explanation:

(x+y)+z=x (y+z)

(1/2+2/3)+1/5=1/2+(2/3+1/5)

7/6+1/5=1/2+13/15

41/30=41/30

Answer 2

Answer:

Step-by-step explanation: This is called the Associative property of groups.

We can verify this by Bodmas

L.HS (1/2+2/3)-(1/5)= 7/6-1/5=29/30

R.H.S 1/2+(2/3-1/5)= 1/2+ 7/15= 29/30
