Answer 3

Calculation of Total Number of Books

To calculate the total number of books brought to the school library, we need to determine the percentages of different types of books and the total number of books represented by each percentage.

According to the information provided, 60% of all books are textbooks, 25% are works of fiction, and the remaining 15 books are dictionaries.

Let's assume the total number of books brought to the library is represented by the variable "x."

To calculate the total number of books, we can set up the following equation:

0.60x (textbooks) + 0.25x (fiction books) + 15 (dictionaries) = x (total number of books)

Simplifying the equation:

0.60x + 0.25x + 15 = x

Combining like terms:

0.85x + 15 = x

Subtracting 0.85x from both sides:

15 = 0.15x

Dividing both sides by 0.15:

15 / 0.15 = x

x = 100

Therefore, a total of 100 books were brought to the school library.

Comparison between Textbooks and Dictionaries

To determine the difference in the number of textbooks and dictionaries, we can subtract the number of dictionaries from the number of textbooks.

The number of textbooks is represented by 60% of the total number of books, which is 0.60 * 100 = 60 textbooks.

The number of dictionaries is given as 15.

Therefore, the difference between the number of textbooks and dictionaries is:

60 textbooks - 15 dictionaries = 45 more textbooks than dictionaries.

So, there were 45 more textbooks than dictionaries brought to the school library.
