the width of a math textbook is 0.75 inches. How many math textbooks can be placed standing up on a shelf that is 18inches wide
the answer is 24 books that are 0.75 inches wide can fit the book shelf.
Hope this help and leave a thumbs up :)
No.
18/0.75 = ?
Every 4 books put in takes up 3 inches, so you could just adding 4 to books and 3 to inches till you're there, 24 0.75 inch books can fit inside an is ince bookshelf.
Hope this helped!
