Question

до ремонта библиотеки книги располагались на 10 стеллажах, по 80 книг на каждом. После ремонта эти же книги разместились на 5  новых стеллажах, поровну на каждом. Сколько книг на каждом новом стеллаже?

Answer 1

Calculation of Books on Each New Shelf

Before the library renovation, the books were arranged on 10 shelves, with 80 books on each shelf. After the renovation, the same books were rearranged onto 5 new shelves, with an equal number of books on each shelf. To determine how many books are on each new shelf, we can divide the total number of books by the number of new shelves.

Let's calculate it step by step:

1. Total number of books before the renovation: 10 shelves * 80 books per shelf = 800 books. 2. Number of new shelves after the renovation: 5 shelves. 3. Number of books on each new shelf: 800 books / 5 shelves = 160 books.

Therefore, after the renovation, there are 160 books on each new shelf.
