A. 1 2/5
B. 5/12
C. 3 cups
D. 4/5 cups
E. 7 cups​

Answer 1

Answer: C. 3 cups

Step-by-step explanation:

Given: In recipe for 5 people, Required Gulf shrimp = $1\dfrac14$ cups

Since, $1\dfrac14=\dfrac{5}{4}$

Required Gulf shrimp = $\dfrac54$ cups

Then, for 1 people Gulf shrimp required = $\dfrac{5}{4}\div 5$

$=\dfrac54\times\dfrac{1}{5}$

$=\dfrac14$ cup

For 12 people, it is required = $12\times\dfrac14 = 3\text{ cups}$

Hence, 3 cups of gulf shrimp is required for new recipe.

So, correct option is C. 3 cups
