    You can set up a proportion for this problem. Let the total number of books = x

    The number of non-fiction books to the total number of books is

    3 / (7 + 3) books = 3/10

    3/10 = 240/x Cross multiply

    3x = 240 * 10 Combine the right

    3x = 2400 Divide by 3

    3x/3 = 2400/3 Divide

    x = 800

    Answer: 800 books in total.
