Anita has written a book of tips on staying healthy. Each book weighs
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)
To find the shipping weight, we need to multiply the weight of each book by the number of books.
12 books * 9/10 of a pound per book = 10 8/10 pounds
To convert this mixed number to an improper fraction, we multiply the whole number (10) by the denominator (10) and add it to the numerator (8), then put that sum over the denominator:
(10 * 10 + 8) / 10 = 108/10
Finally, we can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 2:
108/10 = 54/5
So, the shipping weight, excluding the box, will be 54/5 pounds.
