\n" ); document.write( "\n" ); document.write( "Together = 6.5\r
\n" ); document.write( "\n" ); document.write( "NOTE: 6.5 can be written as a fraction 13/2\r
\n" ); document.write( "\n" ); document.write( "Here is your equation:\r
\n" ); document.write( "\n" ); document.write( "1/10 + 1/x = 13/2\r
\n" ); document.write( "\n" ); document.write( "Can you find x now?
