Which type of numbers results from dividing by 2?

When dividing a whole number by 2, the result can either be a whole number or a decimal, depending on whether the original number is even or odd. However, when we specifically consider the question of what type of numbers result from the division by 2, even numbers consistently yield whole numbers.

Even numbers are defined as integers that are divisible by 2 without leaving a remainder, which means dividing an even number by 2 will always result in another integer. For example, dividing 4 by 2 gives you 2, and dividing 10 by 2 gives you 5. In contrast, when odd numbers are divided by 2, the result is a fraction or decimal (like 3 divided by 2 equals 1.5).

Thus, the correct answer highlights that only even numbers yield whole number results when divided by 2, reinforcing the understanding of even and odd numbers within the context of division.
