If a person reads two chapters a day, with each chapter having 6 pages, and there are 798 pages in total, how many days will it take them to finish reading?

To determine the number of days it will take to finish reading 798 pages, divide the total number of pages by the number of pages read in a day. Since the person reads 2 chapters per day, equivalent to 12 pages per day (2 chapters * 6 pages per chapter), it will take them 798 / 12 = 66.5 days, which is the same as 66 1/2 days. Therefore, the correct answer is 66 1/2, representing the number of days needed to complete reading all 798 pages if two chapters of 6 pages each are read daily.
