A rational number is defined as a number that can be expressed as the quotient of two integers, where the denominator is not zero.
In the case of \( \frac{19}{100} \):
- 19 is an integer (the numerator).
- 100 is an integer (the denominator) and is not zero.
Since \( \frac{19}{100} \) fits the definition of a rational number as it is expressed as the quotient of two integers, the correct answer is:
C. It is the quotient of 19 divided by 100.
