+%28%282x-6%29%2F21%29+%2F+%28%285x-15%29%2F12%29+
factor a 2 from (2x-6) and a 5 from (5x-15)
+%282%28x-3%29%2F21%29+%2F+%285%28x-3%29%2F12%29+
multiply the outsides . multiply the insides. place back in outsides / insides
+%282%28x-3%29%2812%29%29+%2F+%285%28x-3%29%2821%29%29+
this step takes the place of writing the problem horizontially, finding the reciprocal of the second fraction and then multiplying.
next, reduce the fractions by canceling the (x-3)
+%282%2812%29%29+%2F+%285%2821%29%29+
reduce the 12 and 21 by dividing both by 3
+%282%284%29%29+%2F+%285%287%29%29+
multiply
+8%2F35+
