Let x = #cups of flour to make 3 dozen cookies\r
\n" ); document.write( "\n" ); document.write( "Using the ratios: (Cups of flour)/(number of dozens of cookies)\r
\n" ); document.write( "\n" ); document.write( "So we have 3.5/5 and x/3 meaning that\r
\n" ); document.write( "\n" ); document.write( "3.5/5 = x/3
\n" ); document.write( "(3) * (3.5/5) = x
\n" ); document.write( "10.5/5 = x
\n" ); document.write( "2.1 = x\r
\n" ); document.write( "\n" ); document.write( "So the number of cups of flour to make 3 dozen cookies is 2.1 cups.
