the total weight of 5 science textbooks is 6 2/4 pounds. How much does each book weigh?

To find the weight of each book, we divide the total weight of all 5 textbooks by the number of textbooks.

Total weight of 5 textbooks = 6 2/4 pounds

Now, we convert the mixed fraction 6 2/4 to an improper fraction:
6 2/4 = (4 * 6 + 2) / 4 = 26/4

Weight of each book = Total weight of all textbooks / Number of textbooks
Weight of each book = (26/4) / 5

Simplifying the expression:
Weight of each book = (26/4) * (1/5)
Weight of each book = 26/20

Therefore, each book weighs 26/20 pounds.
