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
[tex]\rightarrow 50 \% \text{ of } 800[/tex]
[tex]\rightarrow 50 \% \times 800\\\\\rightarrow \frac{50}{100} \times 800 = 400[/tex]
Thus he gave 400 books to his nephew
