Answer:
Ratio of story books in a library to other books = 1: 7
We know that 1 is a story book our of 1 + 7 = 8 books
So if there is 1 story book then the total number of books = 8
If there is 800 story books then the total number of books = 8 (800) = 6400
Hence, the total number of books in the library is 6400.
