Answer 1

$\bf \begin{array}{ccll} \stackrel{beans}{price}&bag\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 4.59&1\\\\ p&\frac{3}{8} \end{array}\implies \cfrac{4.59}{p}=\cfrac{1}{\frac{3}{8}}\implies \cfrac{4.59}{p}=\cfrac{\frac{1}{1}}{\frac{3}{8}}\implies \cfrac{4.59}{p}=\cfrac{1}{1}\cdot \cfrac{8}{3} \\\\\\ \cfrac{4.59}{p}=\cfrac{8}{3}\implies \cfrac{4.59\cdot 3}{8}=p$
