Answer:
1/4 month per book. other answer options: 0.25 or 25%
Explanation:
If he is reading 8 books in two months, each number can be divided by 2 to get his number of books read in one month.
8/2 = 4
2/2 = 1
4 books per 1 month is equivalent to a quarter of a month per book. This means after each month, he will have 4 books read. After two months, he will have his 8 read.
