All real numbers are irrational. For example, Pi is an irrational number that is a real number. Other irrational numbers can be the square root of an imperfect square.
No. All irrational numbers are real, not all real numbers are irrational.
Every irrational number is a real number.
No. The square root of negative one is an example of an imaginary (not real) number. Pi is irrational, but real.
No, because it could be a rational number.

No. All irrational numbers are real, not all real numbers are irrational.
Every irrational number is a real number.
All irrational numbers are Real numbers - it's part of the definition of an irrational number. Imaginary numbers are neither rational nor irrational. An example of a number that is both Real and irrational is the square root of two. Another example is the number pi.
No. The square root of negative one is an example of an imaginary (not real) number. Pi is irrational, but real.
No, a real number could also be a rational number, an integer, a whole number, or a natural number. Irrational numbers fall into the same category of real numbers, but every real number is not an irrational number.
There can be no such number.
Yes.
Euler's number, e = approx 2.71828
No, because it could be a rational number.
A rational number cannot also be irrational. A real number is either rational, or it is irrational.
Yes, every irrational number is also a real number. Real numbers include all the numbers on the number line, which consists of both rational and irrational numbers. Rational numbers can be expressed as fractions, whereas irrational numbers cannot be expressed as simple fractions. So, while all irrational numbers are real numbers, not all real numbers are irrational—some are rational.
