Rational multiple of a line bundle
I voted to leave this open because while the phrasing is confusing, this is exactly the sort of question a student might ask when they are starting research. In particular, it isn't really a question that would be asked outside of a research environment. I could also imagine some nice answers with nice examples.

Rational multiple of a line bundle
Why require that $m_1$ and $m_2$ are relatively prime, let me not limit myself to $K_X$ also. You can have a Cartier divisor that is torsion in the Picard group but not actually linearly equivalent to zero. Then it is $\mathbb{Q}$linearly equivalent to zero but not itself linearly equivalent to zero. $$\text{ }$$ Definition: on a normal variety, two $\mathbb{Q}$divisors $F,G$ are $\mathbb{Q}$linearly equivalent if $mF \sim mG$ for some integer $m > 0$ so that $mF$ and $mG$ are honest Weil divisors.

Hi Neil, you are right of course. I was thinking to localize at the maximal ideal generated by all the monomials. I'll fix this.
