Step-by-step explanation:
Given ---------*****----------
a = 2 / 3 , b = - 3 / 4 , c = 1 / 2
To prove ----------*********---------
( a * b) * c = a * ( b * c)
L. H. S.
( 2 / 3 x - 3 / 4 ) x 1 / 2
- 6 / 12 x 1 / 2
- 6 / 24
- 1 / 4
Thus L. H. S. = - 1 / 2
R. H. S.
2 / 3 * ( - 3 / 4 x 1 / 2 )
2 / 3 x ( - 3 / 8 )
- 6 / 24
- 1 / 4
Thus R. H. S. = - 1 / 2
L. H. S. = R. H. S.
