Final answer:
Each of the four students received 7 books from Mrs. Rodriguez.
Step-by-step explanation:
The question involves a basic division operation in mathematics. Mrs. Rodriguez brought 28 books to be shared equally among 4 students. To find out how many books each student would receive, we would divide the total number of books by the number of students:
28 books ÷ 4 students = 7 books per student.
So, each student would get 7 books.
