The following are some characteristics of rational numbers: Any two rational numbers can be multiplied, divided, added to, or subtracted from to produce a result that is always a rational number. When the denominator and the numerator are the same integer, the result is still a rational number. When we multiply a rational number by zero, the outcome is the same as the number multiplied by zero. In addition, subtraction, multiplication, and division, rational numbers are regarded as closed.
