----
1 kilobyte = 1000 bytes
1 gigbyte = 1,000,000,000 bytes
----------
book = 400 pages = 400/(2/3) = 600 kilogytes
-----
# of books = 9,000,000,000/600 = 15 million books

you are given that one kilybote of computer memory will hold about 2/3 of a page of a typical text (without formatting).

a typical book has about 400 pages.

2/3 of a page is equal to one kilobyte of memory.

if you take 400 pages and divide them by 2/3 of a page, you will get 400 / (2/3) = 400 * 3/2 = 1200/2 = 600 * 2/3 of a page being contained in a 400 page book.

since 2/3 of a page is handled by one kilobyte of memory, then 600 * 2/3 of a page is equal to 600 kilobytes of memory.

this means that one book requires 600 kilobytes of memory.

1 gigabyte is equal to 1,000 megabytes which is equivalent to 1,000 kilobytes.

that means that 1 gigabyte is equal to 1,000 * 1000 = 1 million kilobytes.

so 9 gigabytes is equal to 9 million kilobytes.

since 1 book requires 600 kilobytes, then you divide 9 million by 600 and you get 15000 books that can fit into a 9 gigabyte flash storage device.

the 9 gigabyte flash storage device can handle thousands of 400 page books.
