\n" ); document.write( "amounts are proportional:\r
\n" ); document.write( "\n" ); document.write( "\"12+ounce+%3A120+milligrams=16+ounce+%3Ax++\"\r
\n" ); document.write( "\n" ); document.write( "\"12++%2Ax++=16++%2A120++\"\r
\n" ); document.write( "\n" ); document.write( "\"12x=16%2A120\"\r
\n" ); document.write( "\n" ); document.write( "\"+x=16%2A120%2F12\"\r
\n" ); document.write( "\n" ); document.write( "\"+x=16%2A10\"\r
\n" ); document.write( "\n" ); document.write( " \"x=160+\" milligrams\r
\n" ); document.write( "\n" ); document.write( "or, you can do it this way:\r
\n" ); document.write( "\n" ); document.write( "if you know a \"12\" ounce cup of coffee has \"120\" milligrams, than you know that \"1\" ounce has \"120+milligrams%2F12=10milligrams\"\r
\n" ); document.write( "\n" ); document.write( "consequently,a \"16\" ounce cup will have \"16%2A10milligrams=160milligrams\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
