Answer: A rational number is the ratio of two whole numbers.
Step-by-step explanation: We all familiar with the concept of rational numbers. A rational number is a fraction, where both the numerator and denominator are whole numbers, and denominator is not equal to zero. Thus, a rational number r can be written as
\(r=\frac{a}{b}(b
eq0 )\).
This can also be written as
\(r=a:b, a~\textup{and}~b\) are coprime.
Thus, we can say from here that -
a rational number is the ratio of two whole numbers, where the second one is not equal to zero.
