3600 : 4 = 900 (книг - это учебники поматематике)
3600 - 900 = 2700 (оставшаяся часть)
2700 : 5 = 540 (словарей)

Problem Analysis

In the given problem, we are told that a total of 3600 books were printed in a day in a printing house. We are also given that one-fourth of these books were textbooks on mathematics, and one-fifth of the remaining books were dictionaries. We need to find out how many dictionaries were printed on that day.

Solution

To solve this problem, we can follow these steps:

1. Find the number of textbooks on mathematics: Since one-fourth of the books were textbooks on mathematics, we can calculate this by dividing the total number of books by 4. 2. Find the number of remaining books: To find the remaining books, we subtract the number of textbooks on mathematics from the total number of books. 3. Find the number of dictionaries: Since one-fifth of the remaining books were dictionaries, we can calculate this by dividing the number of remaining books by 5.

Let's calculate the number of dictionaries using these steps:

1. Number of textbooks on mathematics: 3600 / 4 = 900 textbooks. 2. Number of remaining books: 3600 - 900 = 2700 books. 3. Number of dictionaries: 2700 / 5 = 540 dictionaries.

Therefore, 540 dictionaries were printed on that day.

Answer

In the printing house, 540 dictionaries were printed on that day.
