If Tom can do a job in 2 days, Mike can do the job in 4 days, and Ann can do it in 6 days,
\n" ); document.write( " how long will it take them if they do it together?
\n" ); document.write( ":
\n" ); document.write( "Let t = time required when they all work together
\n" ); document.write( ":
\n" ); document.write( "Let the completed job = 1
\n" ); document.write( ":
\n" ); document.write( "Each will do a fraction of the job, the three fractions add up to 1; therefore:
\n" ); document.write( "\"t%2F2\" + \"t%2F4\" + \"t%2F6\" = 1
\n" ); document.write( ":
\n" ); document.write( "Multiply the equation by 12, results
\n" ); document.write( "6t = 3t + 2t = 12
\n" ); document.write( ":
\n" ); document.write( "11t = 12
\n" ); document.write( "t = \"12%2F11\"
\n" ); document.write( "t = 1\"1%2F11\" hr or 1 hr + \"1%2F11\"*60 = 1 hr 5.45 minutes
\n" ); document.write( ":
\n" ); document.write( ";
\n" ); document.write( "What is the square of 25/9?
\n" ); document.write( "Just square the numerator and the denominator: 625/81
\n" ); document.write( ":
\n" ); document.write( "In case you meant the square root: that's 5/3 \n" ); document.write( "
\n" );
