As a mathematics expert, I am often asked to clarify the relationship between rational numbers and fractions. Rational numbers are a subset of real numbers that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. This definition is fundamental to understanding the nature of rational numbers.
To delve into the question at hand, "Is every rational number a fraction?", we must first define what a fraction is. A fraction is a mathematical expression that represents the division of one integer by another. It is typically written in the form \( \frac{a}{b} \), where \( a \) is the numerator and \( b \) is the denominator. The denominator \( b \) can be any integer except zero, as division by zero is undefined.
Now, let's consider the statement provided: "Since every natural number is an integer. Therefore, \( a \) and \( b \) are integers. Thus, the fraction \( \frac{a}{b} \) is the quotient of two integers such that \( b \neq 0 \)." This is a correct statement. Natural numbers are indeed integers, and any integer can serve as the numerator or denominator in a fraction, provided that the denominator is not zero.
However, the statement that follows, "We know that \( \frac{2}{-3} \) is a rational number but it is not a fraction because its denominator is not a natural number," requires correction. The fraction \( \frac{2}{-3} \) is indeed a rational number and also a fraction. The denominator being negative does not disqualify it from being a fraction; it simply indicates that the value of the fraction is negative. The definition of a fraction does not restrict the denominator to natural numbers only; it can be any integer except zero.
To clarify, every rational number can be expressed as a fraction where both the numerator and the denominator are integers, and the denominator is not zero. This includes positive rational numbers, negative rational numbers, and even zero, which can be expressed as \( \frac{0}{1} \), \( \frac{0}{-1} \), or simply \( 0 \) (though some might argue that zero is not a fraction because it lacks a meaningful numerator).
In summary, every rational number is indeed a fraction. The term "fraction" encompasses all possible quotients of integers where the denominator is not zero, regardless of whether the integers are positive, negative, or zero.

Since every natural number is an integer. Therefore, a and b are integers. Thus, the fraction a/b is the quotient of two integers such that b -- 0. We know that 2/-3 is a rational number but it is not a fraction because its denominator is not a natural number.
