There are rational numbers and Irrational Numbers. Real numbers are DEFINED as the union of the set of all rational numbers and the set of all irrational numbers. Consequently, all rationals, by definition, must be real numbers.
No. Every real number is not a natural number. Real numbers are a collection of rational and irrational numbers.
No. 3.6427 is real and rational, but not a counting number.
Yes.
Yes.
Yes.
Yes it is, but not every real number is a rational number
No. Every real number is not a natural number. Real numbers are a collection of rational and irrational numbers.
Every rational number.
Every integer is also a rational number and a real number.
The set of rational numbers is a subset of the set of real numbers. That means that every rational number is a real number, but not every real number is rational. The square root of 2 is an example of a real number that isn't rational; that is, it can't be expressed as the quotient of two integers.
No
Yes every irrational and rational number is a real number.
Every counting number, and the negative of it, are real, rational integers.
Yes.
No. 3.6427 is real and rational, but not a counting number.
Yes, it is.
Yes.
