Answer 1

Given that Leah's class collected 7 1/2 pounds.

Also it is mentioned that Rihanna's class collected 16 4/5 times as much as Leah's class,

`\begin{gathered} \text{Rihanna's collection=16}(4)/(5)\text{ of Leah's collection} \\ \text{Rihanna's collection=16}(4)/(5)*7(1)/(2) \\ \text{Rihanna's collection=}(84)/(5)*(15)/(2) \\ \text{Rihanna's collection=}(42)/(1)*(3)/(1) \\ \text{Rihanna's collection=12}6 \end{gathered}`

Thus, Rihanna's class collected 126 pounds of food.
