To determine whether -15 is a rational or irrational number, we need to understand the definitions of these terms.
A rational number is any number that can be expressed as a fraction (ratio) of two integers, where the denominator is not zero. For example, 3/4 and -5/2 are rational numbers because they can be written as a fraction of two integers.
On the other hand, an irrational number is a number that cannot be expressed as a fraction of two integers. They are non-repeating, non-terminating decimals. Examples of irrational numbers include √2, π (pi), and e (Euler's number).
In the case of -15, it is a rational number. It can be expressed as -15/1, which is a fraction where the numerator (-15) and denominator (1) are both integers.
So, the answer is that -15 is a rational number.
