7 books to wrap, each 5/6 of a foot long. how long a roll needed 7x12 =84 5/6x7=35/42?

To determine how long a roll is needed to wrap 7 books, each measuring 5/6 of a foot long, follow these steps:

1. Calculate the total length of the 7 books: Multiply the length of one book by the total number of books. The length of one book is 5/6 of a foot, and the total number of books is 7.
5/6 ft/book x 7 books = 35/6 ft

2. Simplify the fraction if desired: The length of the 7 books can be written as 35/6 ft.

So, to wrap the 7 books, a roll with a length of 35/6 feet is needed.
