    Answer - True A rational expression is undefined whenever its denominator is zero. By definition, a rational expression is an expression that can be in the form x/y where x and y are integers and y is not equal to zero. This definition of a rational expression strictly excludes denominators of zero.

    True, rational numbers are normal numbers

    so if you have 1/0 the answer can't be told because you cannot decide one by zero.

    the same is for the irrational number.
