A rectangle has width $\frac34\text{ cm}$ and area $3\frac38\text{ cm}^2$ . Find the length of the rectangle.

Worked solution (try it first)

Length $=$ area $\div$ width.
Write $3\frac38$ as $\frac{27}{8}$ .
Dividing by $\frac34$ means multiplying by $\frac43$ : $\frac{27}{8} \times \frac43 = \frac{9}{2}$ .
So the length is $4\frac12$ cm, option B.
