ASSOCIATIVITY The addition of rational numbers is associative

ASSOCIATIVITY The multiplication of rational numbers is associative.That is if (a)/(b)(c)/(d) and (e)/(f) and (e)/(f) are three rational numbers then ((a)/(b)xx(a)/(d))xx(e)/(f)=(a)/(b)xx((c)/(d)xx(e)/(f))

COMMUTATIVITY The addition of rational numbers is commutative
