Mr. Zelman gave 400 books to his nephew
Solution:
Given that, Mr. Zelman wants to give 50% of his comic book collection to his nephew Alex
Mr. Zelman has 800 comic books
Number of books with Zelman = 800
Mr. Zelman wants to give 50% of books to Alex
Number of books given to nephew = 50 % of books of Zelman
Therefore, we have to find 50 % of 800
![\rightarrow 50 \% \text{ of } 800](https://img.qammunity.org/2021/formulas/mathematics/middle-school/t2ifjo8eg87m27352crq72d9fuy0exwb6f.png)
![\rightarrow 50 \% * 800\\\\\rightarrow (50)/(100) * 800 = 400](https://img.qammunity.org/2021/formulas/mathematics/middle-school/f4fslnp727s4ru8vbsrpsctlsr3wdsarsh.png)
Thus he gave 400 books to his nephew
