Let's pay close attention to the given rate.
\begin{gathered}
\dfrac{8\text{ hr}} {\stackrel{\phantom{\tfrac{1}{2}}}{\small{2\text{ days}}}}
=
\dfrac{28\text{ hr}}{\textcolor{lightblue}{\boxed{\phantom{\dfrac{2}{2}\textcolor{black}{7}}\phantom{\dfrac{2}{2}}} \text{ days}}{\phantom{\text{-}}}}
\end{gathered}
We need to find the number that we can multiply 8 by to get 28.
8* ? =28
We multiply 8 by 72 to get 28, so we will also multiply 2 by 72 to find an equivalent rate.

Multiplying by a Fraction
We want to multiply 2 by 72. To do so, we will move the left factor to the numerator and multiply. Then, let's simplify the result.
