$\"%282x-6%29%2F21\"$ divided by $\"%285x-15%29%2F12\"$ First flip the second rational expression and multiply:
\n" ); document.write( " $\"%28%282x-6%29%2F21%29%2A%2812%2F%285x-15%29%29\"$ Factor
\n" ); document.write( " $\"%282%28x-3%29%2F%283%2A7%29%29%2A%28%282%2A2%2A3%29%2F%285%28x-3%29%29%29\"$ Cancel the numerators and denominators that match.
