A recipe for beef stew calls for 1 pound of beef and 3 potatoes the recipe is doubled to include 2 pounds of beef and 6 potatoes
Lerok [7]

Pounds of beef and potatoes are in ratio or proportion of \frac{1}{3} .

<u>Step-by-step explanation:</u>

Correct Question: A recipe for beef stew calls for 1 pound of beef and 3 potatoes. The recipe is doubled to include 2 pounds of beef and 6 potatoes. Which proportion represents the situation?

We have , A recipe for beef stew calls for 1 pound of beef and 3 potatoes , i.e.

Number of beef stew calls = 1

Number of potatoes = 3

Now , The recipe is doubled to include 2 pounds of beef and 6 potatoes i.e. for every 2 pounds of beef we have 6 potatoes

⇒ 2/6

⇒ \frac{2}{6}

⇒ \frac{2}{2(3)}

⇒ \frac{1}{3}

Therefore , Pounds of beef and potatoes are in ratio or proportion of \frac{1}{3} .
