Question

A bookshelf is 44 inches long. can the sheft hold a set of book, if there are 40 books in the set. and each book averages 8/7 inch. thick? explain your answer

Answer 1

40 x 8/7 = 320/7 = 45 5/7 inches > 44 inches

There's insufficient room for them all to fit

44 divided by 8/7 = 44 x 7/8 = 11x7/2 = 77/2 = 38 1/2 books maximum could fit on the shelf, 38 maximum if you disallow half a book. although if one book was much larger than 8/7 inches, you could fit all the remaining 39 books on the shelf. 8/7 is "just' an average.
