Can a fraction like 5/2 be called even or odd?

Sort of. Parity is not normally defined on fractions. It's usually defined on integers, as well as other commutative rings with ideals of index 2 (eg modular clock arithmetic) and sometimes on lattices (eg chess board squares). read more

Decimals and fractions can not be classified in this category of odd/even. Hence, say, if I round off 3.4 as 3, then it becomes odd. At the same time, if I round 3.4 up to 4, it would make it even. read more

Hi Kenneth. A "fraction" is a whole number over any other whole number except zero. So 6/2 is a fraction. I think you know that it equals 3, which is another whole number and an odd number. So there is an example showing that a fraction can indeed be an odd number. Remember that there are other definitions related to fractions that are more restrictive. read more
