Answer:
Sony place 12 photos on each page.
Step-by-step explanation:
Sony wants to place 64 photos. The remaining ages are 5, so, we just need to distribute 64 photos fro 5 pages, this procedure can be done with a division.
If we divide 64/5, we have 12.8 as a result. However, Sony cannot place 0.8 of a photo, because it represents an incomplete one. So, basically, Sony only can place 12 complete photos, and the remaining space on each page is doesn't enough to an 13th photo.
Therefore, Sony place 12 photos on each page.
