Mary read a 84-page book in 6 days. If she continues reading at that rate, how long will it take her to read a 700-page book?

Answer 1

To find the number of pages Mary can read per day, divide the number of pages in the book by the number of days it took her to read it: 84 pages / 6 days = <<84/6=14>>14 pages/day
To find the number of days it will take Mary to read the larger book, divide the number of pages in the book by the number of pages she can read per day: 700 pages / 14 pages/day = <<700/14=50>>50 days. Answer: \boxed{50}.
