They make a rational number.
Multiply them together.
The sum of two rational numbers is rational.From there, it follows that the sum of a finite set of rational numbers is also rational.

No. The set of real numbers contains an infinitely more irrational numbers than rational numbers.
The answer to an addition problem is called the sum.
Multiply them together.
The sum of two rational numbers is rational.From there, it follows that the sum of a finite set of rational numbers is also rational.
There are more irrational numbers between any two rational numbers than there are rational numbers in total.
Infinitely many. In fact, there are more irrational numbers between them than there are rational numbers.Infinitely many.

Every odd or even number is a rational number, and there are a lot more rational numbers besides those.

Both are part of the real numbers; both are infinite sets. (However, there are more irrational than rational numbers.)Both are part of the real numbers; both are infinite sets.

No. In fact, there are infinitely more irrational numbers than there are rational numbers.
5.68 is rational. All decimal numbers that terminate, or end in one or more repeating digits are rational numbers.
-- There's an infinite number of rational numbers. -- There's an infinite number of irrational numbers. -- There are more irrational numbers than rational numbers. -- The difference between the number of irrational numbers and the number of rational numbers is infinite.
Infinitely many. In fact, between any two different real numbers, there are infinitely many rational numbers, and infinitely many irrational numbers. (More precisely, beth-zero rational numbers, and beth-one irrational numbers - that is, there are more irrational numbers than rational numbers in any such interval.)
No. The set of real numbers contains an infinitely more irrational numbers than rational numbers.
