    Answer with explanation:

    She is incorrect with her statement.

    We know that a product of two rational numbers is always a rational number no matter they are positive or negative.

    Whereas the product of a non-zero rational number and a irrational number is always a irrational number.

    The example which contradicts her statement is:

    If we consider a positive rational number as: 3

    and a negative ration number as: - 2

    The there product i. e.

    3 * (-2) = - 6 which is again a rational number.

    It is incorrect because 20 + (-2) = 18, which is rational.
