Answer: 7/9
Explanation:
To find how many reams of paper the printing press used for each book, we need to divide the total number of reams used by the number of books printed.
Let's convert 2 1/3 reams of paper to an improper fraction:
2 1/3 = (2 × 3 + 1) / 3 = 7/3
So the printing press used 7/3 reams of paper to print 3 books. To find how many reams of paper were used per book, we can divide the total amount of paper used by the number of books:
(7/3) ÷ 3 = 7/9
Therefore, the printing press used 7/9 of a ream of paper for each book.
