    Closure property: For two rational numbers say x and y the results of addition, subtraction and multiplication operations gives a rational number. We can say that rational numbers are closed under addition, subtraction and multiplication.
    Commutative law: For rational numbers, addition and multiplication are commutative.

    Commutative law of addition: a+b = b+a

    Commutative law of multiplication: a×b = b×a
    Associative law: Rational numbers follow the associative property for addition and multiplication.

    Suppose x, y and z are rational then for addition: x+(y+z)=(x+y)+z

    For multiplication: x(yz)=(xy)z.
