    Answers:

    C, D, E

    Step-by-step explanation:

    A rational number is a integer. It is also a terminating or repeating decimal.

    A rational number can be written as a fraction of two integers.

    Answer A is not correct because it’s decimal never ends. It is also not repeating. A cannot be written as a fraction.

    Answer B is not correct because the square root is not a whole number, or a perfect square. The square root has a non-terminating and non-repeating decimal, just like A. B cannot be written as a fraction.

    Answer C is rational because it has a terminating decimal.

    D and E are integers, which also can be written as fractions.

    Out of the options given, C, D, and E have rational numbers, while all others do not.

    The answers are C, D, and E.
