You are using a photocopy machine to reduce an advertisement that is 14 in. wide by 21 in. long. If the new width is to be 8 in., what will the new length be
\n" ); document.write( "Set this up as a proportion;we will call the new length x since we don't know what that is;
\n" ); document.write( "\"14%2F21=8%2Fx\"
\n" ); document.write( "cross multiply;
\n" ); document.write( "14x=8(21)
\n" ); document.write( "14x=168
\n" ); document.write( "x=12
\n" ); document.write( ":)
