1 gallon of juice is equivalent to 128 fluid ounces, so multiply 128 by 3 to get 384.
Thus, the teacher brings 384 fluid ounces of juice on the trip.
Divide 384 by 36 to see how many ounces of juice each student gets.
384/36 = 10 [tex] \frac{2}{3} [/tex]
So, there is only 10 and 2/3 ounces of juice per student, meaning the teacher cannot give each student a full 12-ounce cup.
