The ratio 2:2:5:7 can also be written as
\n" ); document.write( "2x:2x:5x:7x
\n" ); document.write( "That gives us 16 parts total, or
\n" ); document.write( "16x = 304
\n" ); document.write( "x = 19
\n" ); document.write( "so that our ratio becomes
\n" ); document.write( "38:38:95:133
\n" ); document.write( "and there are 95 blue marbles.
\n" ); document.write( "
\n" );
