Question

Which of the following statement is true?

Division of two rational numbers is associative

Division of two rational numbers is not commutative

The multiplication of two rational numbers is not commutative

The subtraction of two rational numbers is associative​

Answer 1

Answer:

(b) Division of two rational numbers is not commutative.

Explanation:

This is true statement because commutative property of division shows that a/b = b/a. But this statement doesn't hold good.

For example :-

Take a = 4 and b =2:-

⇒a/b = b/a

⇒4/2 = 2/4

⇒2 ≠ 0.5.

∴This statement is true.
