With work problems, you must add their
\n" ); document.write( "RATES of working to get their RATE of working together
\n" ); document.write( "( sorry for shouting )
\n" ); document.write( "Tom's rate:
\n" ); document.write( "( 1 job ) / ( 2 hrs )
\n" ); document.write( "Jerry's rate:
\n" ); document.write( "( 1 job ) / ( 3 hrs )
\n" ); document.write( "----------------
\n" ); document.write( "Let \"+t+\" = the time in hrs for them
\n" ); document.write( "to finish the job working together
\n" ); document.write( "This rate is ( 1 job ) / ( t hrs )
\n" ); document.write( "-------------------------
\n" ); document.write( "\"+1%2F2+%2B+1%2F3+=+1%2Ft+\"
\n" ); document.write( "Multiply both sides by \"+6t+\"
\n" ); document.write( "\"+3t+%2B+2t+=+6+\"
\n" ); document.write( "\"+5t+=+6+\"
\n" ); document.write( "\"+t+=+1.2+\" hrs
\n" ); document.write( "----------------
\n" ); document.write( "Every work problem is set up like this,
\n" ); document.write( "they will just be asking for different things\r
