Final answer:
The expression that shows how many photographs are on each page when Cameron splits p photographs evenly among 10 pages is p / 10.
Step-by-step explanation:
Cameron put p photographs into an album and split them evenly among 10 pages. To find how many photographs are on each page, you would divide the total number of photographs by the number of pages. The expression for the number of photographs on each page is p / 10.
This is because if you have a total of p items and you want to distribute them evenly across 10 groups (in this case, pages), you perform division: p divided by 10 yields the number of photographs per page.
