HI there,
\n" ); document.write( "Alma can do a job in 6 days
\n" ); document.write( "Rachel can do the same job in 12 days
\n" ); document.write( "Together:
\n" ); document.write( "1/6 + 1/12 = 1/x
\n" ); document.write( "Common denominator = 12x
\n" ); document.write( "2x + x = 12
\n" ); document.write( "3x = 12
\n" ); document.write( "x = 4 days
\n" ); document.write( "Together they can do the job in 4 days.
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "

\n" );
