Question

the recommended amount of meat to serve 1 and 1/2 dozzen people is 4 and 1/2 pounds. how many pounds of meat are recommended to feed 1 dozzen people? how many pounds are recommended to feed 4 people? and how many pounds are recommended to feed 1 person

Answer 1

First, 1 dozen is 12 units, so

`1(1)/(2)\text{ dozen people }=\text{ 12 people + 6 people = 18 people}`

Now, to solve the exercise you can use the rule of three. So, you have

*How many pounds of meat are recommended to feed 1 dozen people?

`\begin{gathered} 18\text{ people}\rightarrow4.5\text{ pounds} \\ 12\text{ people}\rightarrow x\text{ pounds} \\ x=\frac{12\text{ people }\ast\text{ 4.5 pounds}}{18\text{ people}} \\ x=(54)/(18)\text{ pounds} \\ x=3\text{ pounds} \end{gathered}`

Therefore, 3 pounds of meat is recommended to feed a dozen people.

*How many pounds are recommended to feed 4 people?

`\begin{gathered} 18\text{ people}\rightarrow4.5\text{ pounds} \\ 4\text{ people}\rightarrow x\text{ pounds} \\ x=\frac{4\text{ people }\ast\text{ 4.5 pounds}}{18\text{ people}} \\ x=(18)/(18)\text{ pounds} \\ x=1\text{ pound} \end{gathered}`

Therefore, 1 pound of meat is recommended to feed 4 people.

*How many pounds are recommended to feed 1 person

`\begin{gathered} 18\text{ people}\rightarrow4.5\text{ pounds} \\ 1\text{ person}\rightarrow x\text{ pounds} \\ x=\frac{1\text{ person}\ast4.5\text{ pounds}}{18\text{ people}} \\ x=(1)/(4)\text{ pounds} \end{gathered}`

Therefore, 1/4 pound of meat is recommended to feed 1 person.
