Ben has 165 pictures from his summer trip to Austria he puts 6 pictures on each page of a photo album how many pages did Ben fill?

1 answer

The number of pages filled by Ben can be calculated by dividing the total number of pictures he has by the number of pictures he puts on each page: 165 pictures / 6 pictures per page = <<165/6=27.5>>27.5 pages.
Since we cannot have a fraction of a page, Ben must have filled 27 pages. Answer: \boxed{27}.
