Answer 1

Answer:

4 dozens.

Step-by-step explanation:

Since Ruby, Joey and Sully are baking cookies together, and they need 3/4 cup of flour and 1/3 cup of butter to make a dozen cookies, since Ruby brought 2 cups of flour and 1/4 cup of butter, Joey brought 1 cup of flour and 1/2 cup of butter, sully brought 1 1/4 cups of flour and 3/4 cup of butter, if the students have plenty of other ingredients that they need, to determine how many whole batches of a dozen cookies can they make the following calculation must be performed:

Flour: 2 + 1 + 1 1/4 = (4 1/4) / (3/4) = 4.25 / 0.75 = 5.666

Butter: 1/4 + 1/2 + 3/4 = (1 1/2) / (1/3) = 1.5 / 0.333 = 4.504

Thus, a maximum of 4 dozen cookies can be made.
