long side - 4 * 2.5 = 10
short side - 2 * 3.5 = 7
so 8
What is the GREATEST number of pictures each 2.5-inches by 3.5-inches, that a photographer can print on an 8-inch by 10-inch piece of sensitized paper?
Isn't the answer supposed to be 4, because once you cut it you cannot put it back together.
Please tell me how i'm wrong and how to solve it if i'm wrong. Thanks!
