A can do a piece of work in 3 days and B in 4 1/2 ie 9/2 days then,
\n" ); document.write( "A's one day work is 1/3 and B's one day work is 1/(9/2) => 2/9\r
\n" ); document.write( "\n" ); document.write( "A+B 's one day work = 1/3 + 2/9
\n" ); document.write( "= (3+2)/9
\n" ); document.write( "= 5/9
\n" ); document.write( "A+B can complete the work in 9/5 days or 1 4/5 days
\n" ); document.write( "
\n" ); document.write( "
\n" );
