Final answer:

To find out how many dozen cookies were brought to class on Tuesday morning, multiply the number of students by the amount of cookies each student brought, then divide the total number of cookies by 12 to find the number of dozen cookies.

Step-by-step explanation:

To find out how many dozen cookies were brought to class on Tuesday morning, we need to multiply the number of students by the amount of cookies each student brought. Each student brought 2/3 of a dozen, which is the same as multiplying 2/3 by 12 (since a dozen is equal to 12). So, we have 2/3 * 12 = 8 cookies per student.

To find the total number of cookies brought by all students, we multiply the number of students (31) by the number of cookies per student (8). 31 * 8 = 248 cookies.

Since a dozen is equal to 12, we need to divide the total number of cookies by 12 to find out how many dozen cookies were brought. 248 / 12 = 20.6667 dozen cookies. Rounded to the nearest whole number, this gives us approximately 21 dozen cookies.
