if it's a straight multiplication which is what it looks like then you don't need to find a common denominator.
\n" ); document.write( "all you need to do is multiply all the numerators and multiply all the denominators and you get the answer after reducing to the simplest form.
\n" ); document.write( "formula as i see it is $\"%28-15%2F42%29%2A%281%2F8%29%2A%28-21%2F17%29%2A%28-1%2F17%29\"$
\n" ); document.write( "this becomes $\"%28-15%2A1%2A-21%2A-1%29%2F%2842%2A8%2A17%2A17%29\"$
\n" ); document.write( "which becomes $\"%28-15%2A1%2A-1%2A-1%29%2F%282%2A8%2A17%2A17%29\"$
\n" ); document.write( "the -21 on top was divided into the 42 on the bottom to become -1/2.
\n" ); document.write( "which then becomes $\"-15%2F4624\"$
\n" ); document.write( " \n" ); document.write( "
