Let your sum be a + b = c, where "a" is irrational, "b" is rational, and "c" may be either (that's what we want to find out). In this case, c - b = a. If we assume that c is rational, you would have: a rational number minus a rational number is an irrational number, which can't be true (both addition and subtraction are closed in the set of rational numbers). Therefore, we have a contradiction with the assumption that "c" (the sum in the original equation) is rational.
It is always an irrational number.
Real numbers can be rational or irrational because they both form the number line.
Since the sum of two rational numbers is rational, the answer will be the same as for the sum of an irrational and a single rational number. It is always irrational.
The product of two rational numbers is always a rational number.
yes * * * * * No. Rational and irrational numbers are two DISJOINT subsets of the real numbers. That is, no rational number is irrational and no irrational is rational.
It is always an irrational number.
They are not. Sometimes they are irrational. Irrational numbers cannot be expressed as a fraction.

No. If it was a rational number, then it wouldn't be an irrational number.
Whole numbers are always rational.
yes * * * * * No. Rational and irrational numbers are two DISJOINT subsets of the real numbers. That is, no rational number is irrational and no irrational is rational.
Numbers cannot be rational and irrational at the same time.
No.A rational times an irrational is never rational. It is always irrational.
No, they are complementary sets. No rational number is irrational and no irrational number is rational.Irrational means not rational.
-- 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.
