I have a basic question about rings of fractions.
Let $R$ be a commutative integral domain with quotient field $K$, $\mathfrak p$ a non-zero prime ideal of $R$ and $R_{\mathfrak p}$ the localization of $R$ at $\mathfrak p$.
Is it true that $K$ is also the quotient field of $R_{\mathfrak p}$? If so how I show this?
Thanking you in advance.
