Let's write this out to begin with:

$\frac{15}{124} * \frac{230}{30} / \frac{230}{124}$

Knowing PEMDAS, we know to multiply first:

$\frac{15 * 230}{124 * 30} / \frac{230}{124}$
$\frac{3450}{3720} / \frac{230}{124}$

Now, remember that when you divide by a fraction, we must flip the fraction and multiply so instead of this:

$\frac{3450}{3720} / \frac{230}{124}$

Our equation will look like this:

$\frac{3450}{3720} * \frac{124}{230}$
$\frac{427800}{855600}$

Which simplifies down to:

$\frac{1}{2}$
