Work the two “Try It!” problem on the School Book Page $313$.

Try It!

Find $\frac{1}{4}÷\frac{3}{8}$.

Try It!

How wide is a rectangular strip of land with a length of $\frac{3}{4}$ mile and an area of $\frac{1}{2}$ square mile? Use the area formula: $A=l\times w$.

$\frac{1}{2}=\frac{3}{4}w\to \frac{1}{2}÷\begin{array}{|c|}\hline \\ \\ \hline\end{array}=w\to \frac{1}{2}\times \begin{array}{|c|}\hline \\ \\ \hline\end{array}=w\to w=\begin{array}{|c|}\hline \\ \hline\end{array}$

The strip of land is $\begin{array}{|c|}\hline \\ \hline\end{array}$ mile wide.
