    A number that cannot be irrational is:

    A number that cannot be written as the ratio of two integers

    Step-by-step explanation:

    Irrational numbers can be defined as those numbers which cannot be written as in a form of Fraction (Ration of two integers).

    E. g if we consider the value of constant pi

    π = 3.14159265 ...

    and it goes on, that why we cannot write it in a form of simple fraction.

    Another example of irrational number is under root of 2

    √2 = 1.41421356 ...

    Hence, it also cannot be written as a simple fraction.

    However, a number which can be written as a ratio of two integers is a rational number. e. g

    2/5, 1/4 etc

    As a rational number can never be an irration number, so statement 1 is correct
