In a library, 13 out of 65 books on a bookshelf are non-fiction. If the library has 4,000 books total, how many of those are non-fiction? (use rule of four)

Respuesta :

SJ2006

Ratio of non-fiction to total books = 13/65 = 1/5

Non-Fiction books = 1/5 * total books = 1/5 * 4000 = 800

So, 800 is your answer

52000/65=nonfiction
