Answer 1

Animal books make up (3/20) of all books

Explanation:

Let X be the total number of books, made up of nonfiction, animal, and all others.

(3/5)X are nonfiction books.

Of the nonfiction books, 1/4 are animal books: (3/5)*(1/4)X = (3/20)X are animal books

[This means that Nonfiction, less animal books is: (3/5)X - (3/20)X]

Animal books make up (3/20) of all books.
