Answer:
6. If 580 books were sold at the book fair, 203 of the books were fiction books.
7. If 580 books were sold at the book fair, 87 of the books were comic books.
8. If 580 books were sold at the book fair, 145 of the books were mystery books.
Explanation:
Before solving for the number of books sold for each book genre, first we must know what a percent is. A percentage number is a number expressed as a fraction divided by 100, and it is used to represent how much there is of something out of everything. For example, if you scored 87 on an 100 point test, you would have a score of
or 87%. Likewise, 87% can be rewritten as
or 0.87.
Now that we understand what a percent is, we can solve the following practice problems. For question 6, we know that there are a total of 580 books that were sold at the book fair, and 35% of the 580 books sold were fiction books. Therefore, that must mean that there were a total of 580 × 35% = 580 ×
= 203 fiction books sold. We can now apply this process to questions 7 and 8. There are 580 books sold total, and 15% of them were comic books, so there were a total of 580 × 15% = 580 ×
= 87 comics books sold. Lastly, there were 580 books sold, and 25% of them were mystery books, that means there were a total of 580 × 25% = 580 ×
= 145 mystery books sold.
