always!

Rational numbers can always be expressed as fractions.

They are sometimes - very, very rarely - integers.

If you consider terminating decimals as ones that end in repeating 0s, then the answer is "always".

Sometimes. A rational number is any number that can be written in the form p/q where p and q are integers but q not = 0. So 3 is a natural number and a rational number because it can be written as 3/1. But 1/3 is a rational number only because it will not reduce to a natural (whole) number.

Sometimes. (pi) is non-terminating and irrational. 0.33333... non-terminating is 1/3 , which is rational.

Any and every rational number.

In mathematics a rational number is any number that can be expressed as the quotient a/b of two integers, with the denominator b not equal to zero. Since b may be equal to 1, every integer is a always a part of the rational number group.

Never.
