Answer:
2 1/4 cups
Explanation:
Since we want half as many cookies as the recipe can make, we just half the amount of ingredients used.
Originally, we have 4 1/2 cups of flour for 48 cookies. However, for 24 cookies, which is half of 48, we want to have half of 4 1/2: (4 1/2)/2 = 2 1/4 cups.
Thus, the answer is 2 1/4 cups of flour.
Hope this helps!
