Give the step-by-step reasoning process and then the final answer. Steve decides to read a new book. He reads 100 pages Monday, Wed, and Friday. The book is 2100 pages long. How many weeks does it take to read them all?
He reads 100 * 3 = 300 pages a week. So it would take 2100 / 300 = 7 weeks to read the book.
The final answer: 7.
