False.
No, they are two separate groups of numbers. A number is either rational or irrational, never both.
No. No irrational numbers are whole, and all whole numbers are rational.
It is rational.A number cannot be both rational and irrational.
15 is both rational, and an integer. is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Numbers cannot be rational and irrational at the same time.
It is true and false. It cannot be proved.
No, no number can be both rational and irrational.
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. (However, there are more irrational than rational numbers.)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. (However, there are more irrational than rational numbers.)
Both irrational and rational are real. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
No, they are two separate groups of numbers. A number is either rational or irrational, never both.
It can't be both at the same time. Irrational means "not rational".
No. In fact, a number cannot be both rational and irrational; they're mutually exclusive concepts.
No. No irrational numbers are whole, and all whole numbers are rational.
Real numbers are both. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Integers are rational. In the set of real numbers, every number is either rational or irrational; a number can't be both or neither.
They can be both
The set of real numbers is divided into rational and irrational numbers. The two subsets are disjoint and exhaustive. That is to say, there is no real number which is both rational and irrational. Also, any real number must be rational or irrational.
