Final answer:
Millie will have 14 portions of cheese.
Step-by-step explanation:
To solve this problem, we need to divide the total weight of the block of cheese by the weight of each portion. Millie has a block of cheese that weighs 3.5 pounds and wants to divide it into portions that weigh 1/4 pound. To find the number of portions, we divide 3.5 by 1/4.
First, we need to convert 1/4 pound to decimal form. Since 1/4 is the same as 0.25, we divide 3.5 by 0.25. Dividing 3.5 by 0.25 gives us 14.
Therefore, Millie will have 14 portions of cheese. The correct answer is A) 14 portions.
