Dan has 4 shelves.He has exactly 10 books on each shelf.Judy has 10 shelves. She has exactly 4 books on each shelf. Who has more books?
Dan 10 books x 4 shelves=40
Judy 4 books x 10 shelves=40
They have the same amount of books
10 * 4 = 4 * 10
To determine who has more books, we need to calculate the total number of books each person has.
First, let's calculate the total number of books Dan has:
Dan has 4 shelves, and there are 10 books on each shelf.
So the total number of books Dan has = 4 shelves * 10 books/shelf = 40 books.
Next, let's calculate the total number of books Judy has:
Judy has 10 shelves, and there are 4 books on each shelf.
So the total number of books Judy has = 10 shelves * 4 books/shelf = 40 books.
Both Dan and Judy have the same number of books, 40 books each. They both have the same amount.
