As a mathematical expert, I am well-versed in the principles and properties of rational numbers. Rational numbers are a fundamental concept in mathematics, encompassing all numbers that can be expressed as a fraction where both the numerator and the denominator are integers. The definition of a rational number is quite clear: it is a number that can be written as the quotient of two integers, p and q, with the denominator q not equal to zero. This stipulation is crucial because division by zero is undefined in mathematics; it does not result in a finite number or even an infinite one, but rather leads to an indeterminate form.
The importance of the denominator not being zero cannot be overstated. If the denominator were zero, the fraction would not represent a real number but rather an undefined expression. This is analogous to trying to divide a physical object into zero parts; it's a concept that doesn't make sense in our understanding of the physical world or in mathematics.
Every integer is also a rational number because it can be expressed as a fraction with a denominator of 1. For example, the integer 5 can be written as 5/1. This flexibility in representation is one of the strengths of rational numbers, allowing for a wide range of mathematical operations.
However, it's important to note that while the concept of a rational number is straightforward, there are nuances to consider. For instance, the simplification of fractions is a common practice to express rational numbers in their simplest form. This involves dividing both the numerator and the denominator by their greatest common divisor, if any. Simplification not only makes the number easier to work with but also reveals the true nature of the fraction.
Additionally, rational numbers encompass both finite decimals and repeating decimals. A finite decimal is a number with a limited number of digits after the decimal point, while a repeating decimal has a sequence of digits that repeat indefinitely. Both types of decimals can be expressed as fractions, further demonstrating the versatility of rational numbers.
In summary, the denominator of a rational number cannot be zero because it would render the fraction undefined. Rational numbers are a broad category that includes all integers, finite decimals, and repeating decimals, all of which can be expressed as fractions with non-zero denominators.

In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero. Since q may be equal to 1, every integer is a rational number.
