Answer:
Let R(x) be the predicate "x is a rational number," I(x, y) be the predicate "x can be written as a ratio of two integers," and Q(x, y) be the quantifier "x, y are integers."
The formal statement can be written as follows:
∀x (R(x) → ∃y∃z (Q(y, z) ∧ I(x, y/z)))
This statement can be read as: "For every x, if x is a rational number, then there exist y and z (which are integers) such that y divided by z is a ratio that can represent x."
