Answer 2

Solution:

To solve this problem, we can use the given information to find the number of books with hardcover binding.

Let's denote: - Total number of books as T = 32 - Number of books with softcover binding as S = 7/9 * T

We can then find the number of books with hardcover binding using the equation: Number of books with hardcover binding = Total number of books - Number of books with softcover binding

Calculation:

Given: - Total number of books, T = 32 - Number of books with softcover binding, S = 7/9 * 32

We can calculate the number of books with softcover binding: S = 7/9 * 32 = 28

Now, we can find the number of books with hardcover binding: Number of books with hardcover binding = 32 - 28 = 4

Answer:

So, there are 4 books with hardcover binding.
