Mar can do $\"1%2F5\"$ of the job in a day
\n" ); document.write( "Louie can do $\"1%2F3\"$ in a day
\n" ); document.write( "Together they can do $\"1%2F5+%2B+1%2F3\"$ in a day
\n" ); document.write( " $\"1%2F5+%2B+1%2F3+\"$ = $\"3%2F15+%2B+5%2F15\"$ = $\"8%2F15\"$ per day
\n" ); document.write( " $\"%288%2F15%29+%2A+y+=+1\"$
\n" ); document.write( " $\"y+=+15%2F8\"$
\n" ); document.write( "so it will take 1 and 7/8 day \n" ); document.write( "

\n" );
