Answer:
21 Books in total
Step-by-step explanation:
If you just want the total number of books, here:
If each student has 3 books, and there are 7 students, we can create the equation: 7 * 3 :because this is showing that 7 people each have 3 books
7 * 3 = 21 so There are 21 books in total
Another we could write it is 3 + 3 + 3 + 3 + 3 + 3 + 3 because there are 7 students with 3 books each. Adding this up would equal 21.
