ASSOCIATIVITY The subtraction of rational numbers is not associative i.e. for any three rational numbers `a/b c/d and e/f` we have

ASSOCIATIVITY The addition of rational numbers is associative

COMMUTATIVITY The subtraction of rational numbers is not always commutative.That is

Write any three rational numbers between -2 and 0.

Subtract the rational numbers 3/2 and 8/6 .

Write any three rational numbers between 7.6 and 7.7 .

state true of false Subtraction of rational number is commutative.

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))
