If a fraction is expressed as a fraction, it does not matter what base
is used, its expression is then a quotient of two integers.

If you are talking about the basal (e,g, decimal or octal)
representation of such a quotient the if such a representation
terminates in one base it will also terminate in any multiple of that
base.

For example, any rational whose basal expansion in base 2 terminates
will also have terminating basal expansions in base 4, 6, 8, 10 12, and
so on.

Similarly any rational whose basal expansion in some integer base does
not terminate, will also not terminate with base any integer factor of
that original base.

For example, a rational whose expansion does not terminate in base 10
will also not terminate in either base 2 or base 5.

Anyone of reasonable competence should have been able to work out those
simple rules for themselves.
