Answer: The required number of ounces of fruit snacks that Sam and his friends ate is 9.375.
Step-by-step explanation: Given that Sam and his friends ate [tex]3\dfrac{3}{4}[/tex] bags of fruit snacks and each bag contained [tex]2\dfrac{1}{2}[/tex] ounces.
We are to find the number of ounces of fruit snacks that Sam and his friends ate.
The number of bags of fruit snacks ate by Sam and his friends is
[tex]n_B=3\dfrac{3}{4}=\dfrac{15}{4}[/tex]
and the number of ounces in each fruit bag is
[tex]n_o=2\dfrac{1}{2}=\dfrac{5}{2}~\textup{ounces}.[/tex]
Therefore, the number of ounces that Sam and his friends ate is given by
[tex]n=n_b\times n_o=\dfrac{15}{4}\times\dfrac{5}{2}=\dfrac{75}{8}=9.375.[/tex]
Therefore, the required number of ounces of fruit snacks that Sam and his friends ate is 9.375.
