As a mathematician with a deep understanding of number theory, I can confidently address the question of whether the number 121 is rational or irrational. To begin with, let's define what we mean by rational and irrational numbers.
Rational numbers are numbers that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. In other words, a rational number can be written in the form \( \frac{a}{b} \), where \( a \) and \( b \) are integers, and \( b \neq 0 \).
Irrational numbers, on the other hand, are numbers that cannot be expressed as a simple fraction of two integers. They are typically non-repeating, non-terminating decimals. A classic example of an irrational number is the square root of a non-perfect square, such as \( \sqrt{2} \), or the mathematical constant \( \pi \) (pi).
Now, let's consider the number 121. To determine if it is rational, we need to check if it can be expressed as a fraction of two integers. The reference answer provided suggests that 121 is a rational number because it can be expressed as the quotient of two integers. However, it does not specify which two integers. Let's clarify this.
The number 121 is indeed a rational number. It can be expressed as \( \frac{121}{1} \), which is a valid fraction since both the numerator (121) and the denominator (1) are integers, and the denominator is not zero. This fraction simplifies to 121, which is the number in question.
It's important to note that while 121 can be expressed in this simplified form, it can also be expressed in other equivalent forms that are more complex. For example, \( \frac{121}{1} \) is equivalent to \( \frac{242}{2} \), \( \frac{605}{5} \), and so on. Each of these is a valid representation of the number 121 as a rational number.
The reference answer also implies that there might be a misconception that 121 could be irrational because it is a large number. However, the size of a number does not determine whether it is rational or irrational. Large numbers can be rational, and small numbers can be irrational. The key factor is whether the number can be expressed as a fraction of two integers.
In conclusion, the number 121 is a rational number because it can be expressed as a fraction of two integers, \( \frac{121}{1} \), and it meets the criteria for being a rational number as defined by the properties of rational numbers.
