Is a decimal number, such as 0.345 a fraction? Just by semantics alone, would you consider it a fraction when it is not written in a 'fractional' format?

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 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.

The limit of a sequence
Given
x n = 1 n 2 + 1 + 1 n 2 + 2 + 1 n 2 + 3 + + 1 n 2 + n
Verify if there is or no a limit. Find it if affirmative.
Let a n = n n 2 + 1 (The biggest portion of the sum n times) and b n = n n 2 + n (the smallest portion of the sum n times) then
b n x n a n
b n x n a n
since
lim n n 2 + 1 = lim n n 2 + n = 0 ,
we have that
lim x n = 0.
Is this wrong? why? If it is, any tips on how to find lim x n ? Grateful for any help.
