If there are 9 in total, then he could have a maximum of 3 rows of 3 photos each. 3 x 3 =9.
since this is an open ended question, you can say that there could be 3 photos in each row, and 3 rows. This is so because you need to find 2 numbers that go into 9 evenly, which in this case is 3 x 3. can you please pick my answer as brainliest!!!??? thanks!!
