Give three examples to prove that, if p and q are two integers, then p ÷ q is not necessarily an integer

Given, If p and q are two integers, then p ÷ q is not necessarily an integer. Example 1 : p is 2 and q is 5 but p / q i.e., 2 5 is not an integer Example 2 : p is - 2 and q is 5 but p q i.e., - 2 5 is not an integer Example 3 : p is - 3 and q is - 4 but p q i.e., - 3 - 4 is not an integer. If p and q are two integers, the p ÷ q is not necessarily an integer. Hence, it is proved.
