1 m = 100 cm
100 cm / 2.45 cm = 40.81632653
40.81632653 books cannot be placed on the shelf.
The number of books must be an integer, so it can place 40 books.
100 cm / 2.45 cm = 40.81632653

I think we can round it of and make it 41? That's what i'm thinking now.
Thank you very much for answering and responding!
No, we can not round it of and make it 41.
For 41 books, the shelf length should be:
41 ∙ 2.45 cm = 100.45 cm
For 41 books, the length of the shelf should be greater than 1 m.
For 41 books, the shelf length should be:
41 ∙ 2.45 cm = 100.45 cm
For 41 books, the length of the shelf should be greater than 1 m.
Bosnian is right, unless you wanna balance a book carefully on the edge the answer would have to be 40 books on the shelf
