i believe 1:4.
\n" ); document.write( "there are 3 b's for every a.
\n" ); document.write( "there are 4 c's for every 3 b.
\n" ); document.write( "it would be a direct substitution.
\n" ); document.write( "3b = 1a.
\n" ); document.write( "if b:c were 1:4 it would be a different story.
\n" ); document.write( "then the ratio would be probably 1:12 since for every 1a there would be 3b and for every 1b there would be 4c so 3b would equate to 12c.
\n" ); document.write( " \n" ); document.write( "

\n" );
