Answer:
LHS=RHS
Step-by-step explanation:
Given a = 2/3, b = 4/5 and c = -5/6
(i) a + (b + c) = (a + b) + c: associative property
LHS: 2/3 + (4/5 - 5/6)=19/30
RHS: (2/3 + 4/5) - 5/6 =19/30
LHS = RHS
(ii) a × (b × c) = (a × b) × c
LHS: 2/3 × (4/5 × -5/6) = -4/9
RHS: (2/3 × 4/5) × -5/6 = -4/9
LHS = RHS
