Anita has written a book of tips on staying healthy. Each book weighs 15/16 lb. If she packs 12 books in a box for shipping, what will be the shipping weight, excluding the box? Convert the answer to a mixed number

Answer 1

To find the shipping weight of 12 books, we need to multiply the weight of one book (15/16 lb) by the number of books (12).

(15/16) lb * 12 = 180/16 lb

Now, let's simplify the fraction:

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):

45 ÷ 4 = 11, with a remainder of 1

Therefore, the shipping weight of 12 books is 11 and 1/4 lb (or 11.25 lb).
