COMMUTATIVITY The multiplication of rational numbers is commutative. That is if `a/b and c/d` are any two rational number.

COMMUTATIVITY The multiplication of whole numbers is commutative.

COMMUTATIVITY The addition of rational numbers is commutative

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

Show that subtraction of rational number is not 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))

state true of false Subtraction of rational number is commutative.

Between any two rational numbers there

ASSOCIATITY The subtraction of rational numbers is not asociative i.e.for any three rational numbers (a)/(b)(c)/(d) and (e)/(f) we have

For each pair of rational numbers, verify commutative property of addition of rational numbers : (vi) -2 "and" (3)/(-5)

For each pair of rational numbers, verify commutative property of addition of rational numbers : (v) 3 "and" (-2)/(7)
