To rank the libraries from 1 having the greatest total number of comic books to 5 having the least total number of comic books, we need to first calculate the total number of books in each library.
Let's start by using the information given to find the total number of books in each library:
For Library A, we know that 30 comic books are 2% of its total books. So, we can set up the following equation:
30 = 0.02x
where x is the total number of books in Library A. Solving for x, we get:
x = 1500
Therefore, Library A has a total of 1500 books.
For Library B, we know that 45 comic books are 5% of its total books. So, we can set up the following equation:
45 = 0.05x
where x is the total number of books in Library B. Solving for x, we get:
x = 900
Therefore, Library B has a total of 900 books.
For Library C, we know that 65 comic books are 2% of its total books. So, we can set up the following equation:
65 = 0.02x
where x is the total number of books in Library C. Solving for x, we get:
x = 3250
Therefore, Library C has a total of 3250 books.
For Library D, we know that 75 comic books are 10% of its total books. So, we can set up the following equation:
75 = 0.1x
where x is the total number of books in Library D. Solving for x, we get:
x = 750
Therefore, Library D has a total of 750 books.
For Library E, we know that 90 comic books are 3% of its total books. So, we can set up the following equation:
90 = 0.03x
where x is the total number of books in Library E. Solving for x, we get:
x = 3000
Therefore, Library E has a total of 3000 books.
Now that we have the total number of books in each library, we can rank them based on the number of comic books they have:
Library C: 65 comic books
Library E: 90 comic books
Library B: 45 comic books
Library A: 30 comic books
Library D: 75 comic books
Therefore, the libraries ranked from 1 having the greatest total number of comic books to 5 having the least total number of comic books are: C, E, B, A, D.
