Answer:

$\boxed{\dfrac{y}{x}}$

Step-by-step explanation:

$\dfrac{\dfrac{1}{x} }{\dfrac{1}{y} } \ \text{can also be written as} \ \dfrac{1}{x} \div \dfrac{1}{y}$

-------------------------------------------

$\rightarrow \dfrac{1}{x} \div \dfrac{1}{y}$

<u>Simplifying the expression using "a ÷ b = a x 1/b"</u>

$\rightarrow \dfrac{1}{x} \times y$

$\rightarrow \boxed{\dfrac{y}{x}}$
