6%2Fr+-+5%2F%28r-2+%29+

The LCD in this problem is r%28r-2%29+
Next, you must convert each of the fractions into fractions with denominators r(r-2). You do this by multiplying numerator and denominator of the first fraction by (r-2), and the second fraction by r.

6%2Fr+-+5%2F%28r-2+%29+
%286%2Fr%29%2A%28%28r-2%29%2F%28r-2%29%29+-+%285%2F%28r-2+%29%29%2A%28r%2Fr%29++
+%286r-12+-+5r%29+%2F%28r%28r-2%29%29+

+%28r-12%29%2F%28r%28r-2%29%29+
