Find the reciprocal of $\frac{3}{5}$.

To solve the problem use the division sentence $\frac{8}{9} \div \frac{2}{9}$. This shows how many groups of $\square$ are in $\frac{8}{9}$.

Step 1: To make a bar diagram that represents the amount of Toby's trail mix, divide the $\square$ into sections.

Srep 2: Shade $\square$ of the sections to represent $\frac{8}{9}$ pound.

Step 3: Circle each group of $\frac{2}{9}$ in the shaded section. Determine the number of equal groups of $\frac{2}{9}$.

There are _____ groups of $\frac{2}{9}$ in $\frac{8}{9}$. So, $\frac{8}{9} \div \frac{2}{9}=\square$

Toby can make________ bags of trail mix that each weigh $\frac{\square}{\square}$pound.
