\n" ); document.write( "1 teaspoon = 4.9 ml
\n" ); document.write( ".
\n" ); document.write( "Your proportion is then:
\n" ); document.write( "Let x = grams of expectorant in a teaspoon
\n" ); document.write( "1.5/100 = x/4.9
\n" ); document.write( "x = (1.5*4.9)/100
\n" ); document.write( "x = 7.35/100
\n" ); document.write( "x = .735 grams (or 735 milligrams)
\n" ); document.write( "
