Answer: B. 4/5 cups.
Step-by-step explanation:
Ratio number of--> chocolate chips : <u>dozens of cookies made</u>
--> 4 : <u> 5</u>
The question ask for 1 dozen of cookies. In the ratio above, it states for 5 dozens of cookies.
Our new ratio would be:
Chocolate chips: <u>dozens of cookies made</u>
x : <u> 1</u>
we turn the 5 in the right side of ratio by dividing by 5 so we must do the same for other side of ratio by dividing 5 with 4.
x=4/5
hence answer is B. 4/5 cups
