Solution:
_______________________
Associative property :
a(bc) = (ab)c
_______________________
LHS = 2/5[(-3/7)(2/3)]
= 2/5[ -2/7]
= -4/35 ------(1)
RHS = [(2/5)(-3/7)]*(2/3)
= (-6/35)*(2/3)
= -4/35 ------(2)
From (1) &(2) , we get
LHS = RHS

take the part
2/5*(-3/7*2/3)
=2/5(-2/7)
=-4/35
now take lhs part
{2/5*(_3/7)}*2/3
=(-6/35)*2/3
=-4/35
lhs =rhs
hence proved
