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)

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

answer: howdy

step-by-step explanation:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
