A set of books fills a shelf that is 24in long each book is 3/4 inch thick. How many books are in the classroom shelf?

Would it be 18 ???

No, divide 24 by 3/4. remember you need to multiply by the opposite of the fraction so it is 24 times 4 and dived by 3 :)

answer:32

24 / (3/4)

(24/1) * (4/3) = 96/3 = 32 books

To determine how many books can fit on the shelf, we need to divide the length of the shelf by the thickness of each book.

The length of the shelf is given as 24 inches.

The thickness of each book is given as 3/4 inch.

To divide these two quantities, we can use the formula:

Number of books = Length of shelf / Thickness of each book

Substituting the values:

Number of books = 24 inches / (3/4) inches

To divide by a fraction, we can multiply by its reciprocal. Therefore, (3/4)^-1 = (4/3).

Number of books = 24 inches * (4/3)

Canceling out the units:

Number of books = (24 * 4) / 3

Number of books = 96 / 3

Number of books = 32

Therefore, there are 32 books on the classroom shelf.
