See below.

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

#(6+n)/60=15/90#

We can multiply both sides by #30#.

#(6+n)/2=15/3#

#15/3=5#

So,
#(6+n)/2=5# and #6+n=10#

Thus,

#n=4#.

The answer is 4

#(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
