See below.

To make the problem easier, let's simplify the denominators first.

$\frac{6 + n}{60} = \frac{15}{90}$ $(6+n)/60=15/90$

We can multiply both sides by $30$ $30$ .

$\frac{6 + n}{2} = \frac{15}{3}$ $(6+n)/2=15/3$

$\frac{15}{3} = 5$ $15/3=5$

So,
$\frac{6 + n}{2} = 5$ $(6+n)/2=5$ and $6 + n = 10$ $6+n=10$

Thus,

$n = 4$ $n=4$ .

The answer is 4

$\frac{6 + n}{60} = \frac{15}{90}$ $(6+n)/"60" = 15/90$

      Eliminate fractions -- multiply the left by 90 and the right by 60.

540 + 90n = 900

      Subtract 540 from both sides.

90n = 360

      Divide by 90.

n = 4
