1,583
Step-by-step explanation:
4,861 - 3278 = 1,583. All you have to do is subtract each amount of books from both months.

13 9/10
This is just a math equation. Just add 12 1/2 to 1 2/5 and remember that the bottoms of fractions have to be the same and if you change the bottoms, you have to change the top just as much :)
