\"%281%2F2%29%2Fw=3%2F%285%2F6%29\"
\n" ); document.write( "Cross multiplying gives you:
\n" ); document.write( "\"%281%2F2%29%285%2F6%29=3w\"
\n" ); document.write( "\"%281%2A5%29%2F%282%2A6%29=3w\"
\n" ); document.write( "\"5%2F12=3w\"
\n" ); document.write( "\"%281%2F3%29%285%2F12%29=%281%2F3%29%283w%29\"
\n" ); document.write( "\"%281%2A5%29%2F%283%2A12%29=%283%2F3%29w\"
\n" ); document.write( "\"5%2F36=1w\"
\n" ); document.write( "\"highlight%28w=5%2F36%29\"
\n" ); document.write( "It's better to give fractional answers when given fractional equations and decimal answers when given decimal equations. That's a rule of thumb, some teachers are more precise than others.
