    2.777777 and - 7/3

    Step-by-step explanation:

    If a number can be defined in the form of p/q where q≠0, then it is called rational number.

    If a decimal number is repeating then it is a rational number because it can be written in the form of p/q.

    For example: 1.222, 3/5, 2.5, - 1/2, 4.0707007 ...

    All real numbers which are not rational numbers are called irrational numbers.

    For example: 0.2357835 ..., √2, π.

    In the given numbers,

    Rational numbers = 2.777777, - 7/3

    Irrational numbers = 2.7182818459 and √3

    Therefore the two rational numbers are 2.777777 and - 7/3.
