Problem

A rational number between $\sqrt{2}$ and $\sqrt{3}$ is:

$\textbf{(A)}\ \frac{\sqrt{2} + \sqrt{3}}{2} \qquad \textbf{(B)}\ \frac{\sqrt{2} \cdot \sqrt{3}}{2}\qquad \textbf{(C)}\ 1.5\qquad \textbf{(D)}\ 1.8\qquad \textbf{(E)}\ 1.4$

We see that $A$ and $B$ are both irrational, so we look at $C, D,$ and $E$ Recall that $\sqrt 2$ is around $1.414$ , and $\sqrt{3}$ is around $1.732$ So the only number between that is $\boxed{\textbf{(C) }1.5}$
