document.write( "Question 278113: it takes 5 men 3 hours to do a job if 3 men do the same job how long will it take
\n" );
document.write( "OK You want to find out what the MANHOURS ARE. 5x3=15 (If it took them 3DAYS, you would then use MANDAYS, which would be 15 MANDAYS.) Since you now only have 3 men doing the job, simply divide: 15 MANHOURS/3 (MEN), LEAVING YOU WITH 5 hours the three men will take to do the same job that 5 men did on only three hours! (First 'gut' observation is that with less men, it will take a longer time.) \n" );
