Calculation of the Difference in the Number of Books between the Two Libraries

To calculate the difference in the number of books between the two libraries, we need to determine the total number of books in each library and then find the difference.

According to the information provided, the first library has 12,000 books, which represents 80% of the total number of books in the second library.

To find the total number of books in the second library, we can use the following formula:

Total number of books in the second library = (Total number of books in the first library) / (Percentage of books in the first library) * 100

Substituting the given values into the formula:

Total number of books in the second library = (12,000) / (80%) * 100

Calculating this, we find that the total number of books in the second library is 15,000.

To find the difference in the number of books between the two libraries, we subtract the total number of books in the first library from the total number of books in the second library:

Difference = Total number of books in the second library - Total number of books in the first library

Difference = 15,000 - 12,000

Therefore, the second library has 3,000 more books than the first library.

Answer: The second library has 3,000 more books than the first library.
