Answer: 9 pages in the photo album will be completely filled.
Explanation:
To determine how many pages of the photo album will be completely filled, we need to divide the total number of pictures by the number of pictures per page:
73 pictures ÷ 8 pictures per page = 9.125
Since we can't have a fraction of a page, we need to round up to the nearest whole number.
9.125 rounded to the nearest whole number is 9.
