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.(1 point)
$$
The total weight of the books is 12 * 15/16 lb = 180/16 lb.
To convert this to a mixed number, we divide the numerator (180) by the denominator (16).
180 ÷ 16 = 11 with a remainder of 4.
Thus, the shipping weight, excluding the box, is 11 4/16 lb.
We can simplify this mixed number by dividing both the numerator and denominator by their greatest common factor, which is 4.
11 ÷ 4 = 2 with a remainder of 3.
4 ÷ 4 = 1.
Therefore, 11 4/16 can be simplified to 2 3/4.
So, the shipping weight, excluding the box, is 2 3/4 lb. Answer: \boxed{2\frac{3}{4}}.
