if 6 men/14 days than, than x men/21 days [set-up as a proportion problem]
\n" ); document.write( "6 men/14 days = x men/21 days [set the ratios equal to each other and cross-multiply]
\n" ); document.write( ".
\n" ); document.write( "(6)(21)=14x
\n" ); document.write( "126=14x [solve for x]
\n" ); document.write( "x=9
\n" ); document.write( ".
