Ms. Spilker wrote a book on pickleball strategy. Each book weighs 13/16 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
The weight of one book is 13/16 lb.
The weight of 12 books is (13/16)(12) = 156/16 lb.
To convert this to a mixed number, we divide 156 by 16.
Dividing 156 by 16 gives 9 with a remainder of 12.
So, the shipping weight, excluding the box, is 9 and 12/16 lb.
Simplifying the fraction gives 9 and 3/4 lb. Answer: \boxed{9 \dfrac{3}{4}}.
