In the following inequality
$$\frac{1+c}{a+b}\leq\varphi$$
how do I say it in English?
I think that I should say: "The ratio of the sum of $1$ and $c$ to the sum of $a$ and $b$ is less than or equal to phi."
Is the Greek letter, phi, used to represent the golden ratio so that the meaning of the inequality is, "The ratio of the sum of $1$ and $c$ to the sum of $a$ and $b$ is less than or equal to the golden ratio."

$\begingroup$Say: "One plus cee over ay plus bee is at most equal to phee$\ \ldots$"$\ \ $ If $\phi$ has been defined before (e.g., is an angle in some figure) that's it. If $\phi$ is meant to be the golden ratio, close your sentence with "where phee is the number $(\sqrt{5}-1)/2$, also called golden ratio".
