As others have pointed out in the comments, there may be contradictory definitions, and it depends on what the context is.
That being said, have a look at the description of the tag you used for the question:
(fractions): Questions on fractions, i.e. expressions (not values) of the form $\frac{a}{b}$, including arithmetic with fractions. Not to be confused with the tag (rational-numbers): fractions denote rational numbers, but the same rational number may be written in different ways as a fraction.
So $0.345$ is definitely a rational number, but in its current form is not a fraction according to this description.
