If $\frac{p}{p+q}$ is a negative real number, what can I deduce about complex $p$ and $q$? [closed]

Let $p, q$ be complex numbers with non-negative real parts and arbitrary imaginary parts. If $\frac{p}{p+q}$ is a negative real number, what can I deduce about $p$ and $q$? Motivation: This question ...

Is $\partial (\liminf_{n}\sum_{t=1}^{n}a_{t})/\partial a_{t} = 1$ for every $t \in \mathbb{N}$? [closed]

If we do not impose any conditions on the real sequence $(a_{t})$ other than that $a_{t} \geq 0$ for all $t$, is it necessarily true that for every $t \in \mathbb{N}$ we have $\partial (\liminf_{n}\...
