Multiply the amount of lollipops and the weight of each lollipop to find the total weight:
[tex]7\cdot\frac{1}{3}=\frac{7}{3}[/tex]Since 7 is greater than 3, rewrite 7 as 6+1 to write the improper fraction as a mixed fraction:
[tex]\begin{gathered} \frac{7}{3}=\frac{6+1}{3} \\ =\frac{6}{3}+\frac{1}{3} \\ =2+\frac{1}{3} \\ =2\frac{1}{3} \end{gathered}[/tex]Therefore, the costumer receives 2 1/3 ounces.
