If Sam can do a job in 4 days that Lisa can do in 6 days and Tom can do in 2 days, how long would the job take if Sam, Lisa and Tom worked together to complete it ?
\n" ); document.write( "-----------------------
\n" ); document.write( "Sam does 1/4 job per day.
\n" ); document.write( "Lisa does 1/6 per day.
\n" ); document.write( "Tom does 1/2 per day.
\n" ); document.write( "Add those.
\n" ); document.write( "1/4 + 1/6 + 1/2 = 11/12
\n" ); document.write( "Together, they do 11/12 of the job per day, so it takes 12/11 days.
\n" ); document.write( "Together, 12/11 days.
\n" ); document.write( "
\n" );
