is an example to show that

The question is incorrect.

In place of it shoulb be .

⇒Now the question becomes ) {Here a = ,b = }

⇒ Now the operation performed is a + b = b + a

⇒This is commutative property of rational numbers

⇒ Hence option a is answer.

(b)Incorrect the number obtained on the right side is not the added value, It has been changed from a + b to b + a.

(c)Incorrect the property is an example of commutativity not associativity.

{Associative property for addition - a + (b + c) = (a + b) + c}.

(d)Incorrect it’s not an example of distribution or distributive Property.

{Distributive property - a×(b + c) = a×b + a×c
