You can put this solution on YOUR website!
A ratio of two numbers is like a fraction \"a%2Fb\".\r
\n" ); document.write( "\n" ); document.write( "A proportion is a ratio of two numbers equal to a ratio of two other numbers:
\n" ); document.write( "\"a%2Fb+=+c%2Fd+\". So, I would say that the ratio is \"2%2F5+=+a%2F15\". I suppose if \"n=1%2F2\" had been written in the form \"n%2F1=1%2F2\", then that too would have been an example of a proportion.\r
