    Answer:

    25, 2, & 3 are rational numbers

    π is a irrational number.

    Explanation:

    I think we need to find out the irrational number.

    Here we learn main difference between rational and irrational number.

    Rational Number:

    All numbers whose written in fraction form where numerator and denominator are whole number.

    All the whole numbers are rational number.

    For example: 2 (because we can write 2 as  \frac{2}{1}  ),  \frac{5}{6}  etc

    0.666666…. (endless repeating digits)

    In given question: 25, 2 and 3 are rational numbers

    Irrational Numbers:

    All numbers that are not rational are considered irrational. An irrational number can be written as a decimal form, but not as a fraction form.

    An irrational number has endless non-repeating digits to the right of the decimal point.

    π = 3.141592…… (endless non repeating digits)

    √2 =1.414213… (endless non repeating digits)
