Yes, the statement is true. A rational number is defined as any number that can be expressed in the form of a fraction, where the numerator and the denominator are both integers, and the denominator is not zero.
For example, the number 1/2 is a rational number because it can be written as a ratio of the integers 1 and 2. Similarly, the integer 4 can also be considered a rational number since it can be expressed as 4/1, which is a ratio of the integers 4 and 1.
This concept is fundamental in mathematics as it helps to categorize numbers based on their properties. Rational numbers include both positive and negative values, as well as zero, and they can be expressed in decimal form, either terminating (like 0.5) or repeating (like 1/3, which is 0.333…). Understanding rational numbers is essential for various mathematical operations and concepts.
