Final answer:
To find the weight of one book from 6 books weighing 8 2/5 pounds in total, convert to an improper fraction (42/5 pounds) and divide by 6 resulting in 7/5 pounds per book (choice B).
Step-by-step explanation:
The question asks how to determine the weight of one book if 6 books in a box weigh a total of 8 2/5 pounds. To find the weight of each book, we will divide the total weight of the books by the number of books.
First, let's convert 8 2/5 pounds to an improper fraction for easier calculations. This is equal to 42/5 pounds. Now, we divide this by 6 to find the weight of one book:
42/5 pounds ÷ 6 = 42/5 × 1/6 = 42/30 = 7/5 pounds
Therefore, the weight of one book is 7/5 pounds, which corresponds to choice B.
