Every year in January, Natalia, the librarian, tidies up the books. She has 145 novels, 271 comics, 419 documentaries, and 209 albums to store. She wants to put these in crates that can hold 9 items. How many crates will Natalia use?
Let’s first calculate the total number of items: 145 + 271 + 419 + 209 = <<145+271+419+209=1044>>1044 items
Now let’s put the items in the crates: 1044 / 9 = <<1044/9=116>>116 crates
