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.
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. The weight of one book is 15/16 lb and she packed 12 books in the box.
So, the total weight of the books would be (15/16) * 12 = 180/16 = 11 4/16 = 11 1/4 lb.
Therefore, the shipping weight of the books, excluding the box, is 11 1/4 lb.
To find the shipping weight of 12 books, we need to multiply the weight of one book by 12.
Weight of one book: 15/16 lb
Shipping weight of 12 books: (15/16 lb) * 12
To multiply fractions, we multiply the numerators and then the denominators:
Shipping weight of 12 books: (15 * 12)/(16 * 1) lb
Simplifying the numerator and denominator separately:
Shipping weight of 12 books: 180/16 lb
Now, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 4:
Shipping weight of 12 books: (180 ÷ 4)/(16 ÷ 4) lb
Shipping weight of 12 books: 45/4 lb
Lastly, let's convert the improper fraction to a mixed number:
Shipping weight of 12 books: 45 ÷ 4 lb = 11 remainder 1/4 lb
Therefore, the shipping weight of 12 books, excluding the box, will be 11 1/4 lb.
To find the shipping weight of 12 books, we need to multiply the weight of one book by the number of books.
The weight of one book is 15/16 lb.
So, to find the weight of 12 books, we can multiply 15/16 by 12:
(15/16) * 12 = (15 * 12)/(16 * 1) = 180/16
Now, we need to simplify the fraction. The greatest common divisor of 180 and 16 is 4:
180/16 = (180/4) / (16/4) = 45/4
Now, let's convert the improper fraction 45/4 to a mixed number:
45 divided by 4 gives us a whole number of 11 with a remainder of 1.
Therefore, the mixed number representation of 45/4 is 11 1/4.
So, the shipping weight of 12 books, excluding the box, will be 11 1/4 pounds.
