Sally

Sally is making 15 individual blueberry cheesecakes. How many pounds of blueberries will be in each cheesecake if 5 1/4 pounds of blueberries are divided equally among them?

Correct answer:

x =  7/20 lb

Step-by-step explanation:

$$\begin{gathered} n=15 \\ b=5\frac{1}{4}=5+\frac{1}{4}=\frac{5\cdot 4+1}{4}=\frac{20+1}{4}=\frac{21}{4}=5.25\text{pd} \\ x=b/n=\frac{21}{4}/15=\frac{21}{4\cdot 15}=\frac{21}{60}=\frac{7}{20}\text{lb}=0.35\text{lb} \end{gathered}$$
