\"5%2F8%2B3%2F10-1%2F4\"\r
\n" ); document.write( "\n" ); document.write( "Must find common denominator, in this case it is 80.\r
\n" ); document.write( "\n" ); document.write( "so we have \"5%2F8%2B3%2F10-1%2F4\" becomes \"50%2F80%2B24%2F80-20%2F80\"\r
\n" ); document.write( "\n" ); document.write( "then we add and subtract to get \"54%2F80\" reduce to lowest terms by dividing top and bottom number by 2 to get \"27%2F40\"\r
\n" ); document.write( "\n" ); document.write( "Answer:\r
\n" ); document.write( "\n" ); document.write( "\"27%2F40\"
