\n" ); document.write( "Sue can sew 1 dress in 3 hours: 1/3
\n" ); document.write( "Helen can sew 1 dress in 2 hours: 1/2

\n" ); document.write( "The LCD is 2*3*t=6t. If you multiply everything by the LCD you can clear your fractions:
\n" ); document.write( "\"6t%281%2F3%29%2B6t%281%2F2%29=6t%281%2Ft%29\"
\n" ); document.write( "\"2t%2B3t=6\"
