Questions & Step-by-Step Solutions
In a library, 50 books are fiction, 30 are non-fiction, and 10 are both. How many books are only fiction?
Step 1: Identify the total number of fiction books. In this case, there are 50 fiction books.
Step 2: Identify the number of books that are both fiction and non-fiction. Here, there are 10 books that are both.
Step 3: To find the number of books that are only fiction, subtract the number of books that are both from the total number of fiction books. So, calculate 50 (total fiction) - 10 (both) = 40.
Step 4: The result is that there are 40 books that are only fiction.
