always!

Rational numbers can always be expressed as fractions.

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.

All integers are rational numbers, but not all rational numbers are integers.2/1 = 2 is an integer1/2 is not an integerRational numbers are sometimesintegers.
