Explanation:
we know that
To find out the unit rate in pitchers per bag, divide the total of pitchers of orange by the total bags of oranges
Let
x ----> the total of pitchers of oranges
y ----> the total bags of oranges
z ----> the unit rate in pitchers per bag
![z=(x)/(y)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ayhl0qe7p6eghteqpz358y0g1uifu6qmpv.png)
we have
![x=(3)/(4)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vq399egcjt0rxzbfil8yfcxx3ws5b18i5p.png)
![y=(1)/(12)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/1qc5y3emyjzk98st3a8j1z8j4xxuwd0mwu.png)
substitute
![z=((3/4))/((1/12))](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vbnd6vkc7nczxa9wt9xxmasin04pyuc8mn.png)
![z=(36)/(4)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ch5vmlg6j88kx90kjlfv7k5wghdxmf8nwu.png)
![z=9\ (pitchers)/(bag)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ppdvv5ud6kswlwffrypkmcixg80nhx9e79.png)
