The total weight of 5 science textbooks is 6 2/3 pounds how much does each book weigh?

To find the weight of each book, we need to divide the total weight by the number of books.

Total weight = 6 2/3 pounds
Number of books = 5

To divide 6 2/3 pounds by 5, we first need to express 6 2/3 as an improper fraction.

6 2/3 = (6 * 3 + 2) / 3 = 20/3

Now, we can divide 20/3 by 5.

(20/3) / 5 = 20/3 * 1/5 = 20/15 = 4/3

Therefore, each science textbook weighs 4/3 pounds.
