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}}
