If 6 men can do the job in 14 days, it will take 1 man 6 times as long
\n" ); document.write( "so. 1 man will take $\"6%2A14+=+84\"$ days
\n" ); document.write( " $\"x%2F21+=+1%2F84\"$
\n" ); document.write( "You can read this as: what part of the job can be done by 1 man in 21 days
\n" ); document.write( "if 1 man can do 1 job in 84 days
\n" ); document.write( " $\"x+=+1%2F4\"$
\n" ); document.write( "So, 1 man can do 1/4 of the job in 21 days
\n" ); document.write( "And 4 men can do 4 times as much, or 1 job, done in the same amount tof time
\n" ); document.write( "It takes 4 men to do the job in 21 days\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
