You can put this solution on YOUR website!
if sam can do a job in 4 days that lisa can do in 6 days and tom can do in two days, how long would the job take if sam, lisa ,and tom worked together to completed
\n" ); document.write( ":
\n" ); document.write( "Let t = time required when all worked
\n" ); document.write( "Let the completed job = 1
\n" ); document.write( ":
\n" ); document.write( "A typical shared work equation, each will do a fraction of the job, the 3 fractions add up to 1
\n" ); document.write( " $\"t%2F4\"$ + $\"t%2F6\"$ + $\"t%2F2\"$ = 1
\n" ); document.write( "Multiply by 12
\n" ); document.write( "12* $\"t%2F4\"$ + 12* $\"t%2F6\"$ + 12* $\"t%2F2\"$ = 12
\n" ); document.write( "Cancel out the denominators and you have:
\n" ); document.write( "3t + 2t + 6t = 12
\n" ); document.write( "11t = 12
\n" ); document.write( "t = $\"12%2F11\"$
\n" ); document.write( "t = 1.09 days, or 1 day + .09(24) = 1 day 2.2 hrs \n" ); document.write( "

\n" );
