Joan has 41 books, each 2.45 cm thick. How many books can she place in an one meter shelf long?
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.
Note... please explain....
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.
Answer: 40.8163...
Solution:
2.45÷100=0.0245
1÷0.0245=40.816326...
