Dog food 5

Maria works at a kennel and uses 30-pound bags of dog food to feed the dogs. If each dog gets 2/5 pound of food, how many dogs can she feed with one bag?

Final Answer:

n =  75

Step-by-step explanation:

$$\begin{gathered} a=30\text{lb} \\ b=\frac{2}{5}=0.4\text{lb} \\ n=a/b=30/\frac{2}{5}=30:\frac{2}{5}=30\cdot \frac{5}{2}=\frac{30\cdot 5}{2}=\frac{150}{2}=75 \end{gathered}$$
