um... somthing is lost in ur translation of the problem as this reads -6 divided by 1 divided by 4 which is -6/4 which is -3/2=n
\n" ); document.write( "and -7/1/3 => -7/1=-7 then -7/3=m
\n" ); document.write( "to solve this you would have to set them as proportionate to each other
\n" ); document.write( "when n=-3/2 then m=-7/3
\n" ); document.write( "so -3/2 is to -7/3 as 2 is to m
\n" ); document.write( " $\"%28-3%2F2%29%2F%28-7%2F3%29=2%2Fm\"$
\n" ); document.write( "cross multiply
\n" ); document.write( " $\"2%28-7%2F3%29=%28-3%2F2%29m\"$
\n" ); document.write( " $\"-14%2F3=-3m%2F2\"$
\n" ); document.write( "multiply both sides by a common denominator the fastest is what the two denominators multiply together to make which in this case 3 times 2 is 6
\n" ); document.write( "also since both numbers are negative and we want a positive m answer make it a -6\r
\n" ); document.write( "\n" ); document.write( "

\n" ); document.write( " $\"28=9m\"$
\n" ); document.write( " $\"28%2F9=m\"$
\n" ); document.write( " $\"3.1111=m\"$ \n" ); document.write( "

\n" );
