Answer:
Rational numbers are fractional numbers, whose numerator and denominator are integers and the denominator is ever zero.
Step-by-step explanation:
The sum of rational numbers gives a rational number;
     +
  +  =
 =  , because the evaluation of the denominator always results to a non-zero integer.
 , because the evaluation of the denominator always results to a non-zero integer.
The product of   x
 x  =
 =  , which multiply both numerator and denominator to give integer numbers.
, which multiply both numerator and denominator to give integer numbers.
The sum and product of rational and irrational numbers are always irrational numbers, for instance,
             x 7 = 2.3 , which is a number which decimal points that can only be represented by the product irrational number and rational number , where 7 is an irrational number.
 x 7 = 2.3 , which is a number which decimal points that can only be represented by the product irrational number and rational number , where 7 is an irrational number.
         + 7 =  7
 + 7 =  7 , which is a whole number and fractional number combined.
 , which is a whole number and fractional number combined.
