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.
The product of x = 
, 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.
+ 7 = 7 , which is a whole number and fractional number combined.
The answer is (7/9, -5/9)
(7 over 9 and negative 5 over 9)
Idk, why does the world need problems like this, not like everyone is going to grow up to be a math teacher.
