#### Answer:

Each book is 2.3 inches thick.

#### Explanation:

To solve this equation, you divide 27.6 by 12 (27.6/12). You will find that each of the books is 2.3 inches thick.

The reason why you have to divide 27.6 by 12 to find your answer is that the total width is 27.6 inches, and you want to know how much of the total does each of the 12 books take up.
