Answer
$\frac{10}{24}$
Work Step by Step
We are trying to write $\frac{5}{12}$ with a denominator of 24. In order to do this, we must first divide 24 by the current denominator.
$24\div12=2$
Therefore, we must multiply both the numerator and denominator of the original fraction by 2.
$\frac{5\times2}{12\times2}=\frac{10}{24}$
