To find the total weight of the books in the box, we need to multiply the weight of one book by the number of books in the box: 15/16 lb/book * 12 books = 180/16 lb.
To simplify the fraction, we can divide both the numerator and denominator by the greatest common divisor, which is 4: 180/16 lb = (180/4) / (16/4) lb = 45/4 lb.
To convert this improper fraction to a mixed number, we divide the numerator (45) by the denominator (4), which gives us a quotient of 11 and a remainder of 1: 45/4 = 11 1/4.
Therefore, the shipping weight of the books, excluding the box, is 11 1/4 lb.
