This is my code

```
\begin{enumerate}[(i)]
\item  $\frac{1}{2}$  \text{VS}  \displaystyle \frac{1}{2}\\
\item $\sum_{k=0}^{n} f(k)$ \text{ VS }  \displaystyle \sum_{k=0}^{n} f(k) \\
 \item  $\int_{1}^{2} f(x)dx$ \text{ VS } \displaystyle \int_{1}^{2} f(x)dx
 \end{enumerate}

```

And it ends up like this

How can I fix it?
