Answer:
32 books are none fiction.
Step-by-step explanation:
If %60 of her books are fiction that means that 40% are nonfiction (since in total there are 100% books and 60% are fiction which means that the rest is non-fiction). In order to find 40%, we just multiply the total amount of books by 0.4, and so we get...
80 x 0.4 = 32
Therefore 32 books are none fiction.
