One job is \"paint the neighbor's house\".
\n" ); document.write( "Basic idea, RT=J
\n" ); document.write( "R, workrate
\n" ); document.write( "T, time
\n" ); document.write( "J, amount of job\r
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "PERSON      RATE        TIME        JOB\r\n" );
document.write( "  A          5r                      1\r\n" );
document.write( "  B          r                       1\r\n" );
document.write( " both       1/7          7           1\r\n" );
document.write( "

\n" ); document.write( " $\"5r%2Br=1%2F7\"$ , their rates combined working together\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"6r=1%2F7\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"highlight%28r=1%2F42%29\"$ , person B would need 42 days, working alone.\r
\n" ); document.write( "\n" ); document.write( " $\"5%2F42\"$ $\"jobs%2Fday\"$ , about $\"highlight%288.4%29\"$ days person A would need working alone. \n" ); document.write( "
