conversations.value: Jack has a stack of books that is 12 inches thick. He knows from experience that 80 pages is one inch thick. If he has 6 books, how many pages is each one on average?
  Give me a clear explanation.

conversations.value: There are 960 pages because 80 x 12 = 960
  Each book is 160 pages because 960 / 6 = 160
