Rodney has four books.She shares it with her two friends for one book each.They give her 14 books back and she spends it with her other 7 friends. How many books did they each get back?

To find out how many books each friend received back, we need to follow these steps:

1. Start with Rodney's initial four books.
2. Rodney shares her books with her two friends, giving one book to each friend. Thus, Rodney now has 4 - 2 = 2 books left.
3. Her two friends each give her back 14 books, so now Rodney has 2 + 14 = 16 books.
4. Rodney then spends her books with her other 7 friends. Hence, she gives out a total of 16 books.
5. To find out how many books each friend received back, divide the total number of books Rodney spent (16) by the number of friends she shared books with (7).
16 books / 7 friends = 2.28 books per friend (approximately).

Therefore, each friend received approximately 2.28 books back from Rodney.
