Final answer:
Cora can make 12 batches of cookies with her 3 cups of sugar by dividing the total amount of sugar she has (3 cups) by the amount of sugar needed for one batch (1/4 cup).
Step-by-step explanation:
To determine how many batches of cookies Cora can make with her 3 cups of sugar, we need to use division to calculate the number of batches.
Each batch of cookies requires 1/4 cup of sugar. To find out how many batches she can make, we divide the total amount of sugar Cora has by the amount required per batch.
So, the calculation is:
Determine the total cups of sugar Cora has: 3 cups.
Determine the amount of sugar required per batch of cookies: 1/4 cup.
Divide the total amount of sugar by the amount required per batch: 3 cups ÷ 1/4 cup per batch = 12 batches.
Cora can make 12 batches of cookies with her 3 cups of sugar.
