Best Answer

No. Real numbers are equivalence classes of cauchy sequences of rational numbers, which in turn are equivalence classes of pairs of integers (or whole numbers). Examples of real numbers that are not rational and therefore not integer are sqrt(2) and pi. Examples of real numbers that are rational but not integer are 1/2 and 13/17.

YES. Every whole number is a real number too.

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.

Yes. The set of whole numbers (more usually called Integers) is a strict subset of the set of Real Numbers.

Neither.For any whole number there is a real number which is bigger and for any real number there is a whole number which is bigger.

A whole number IS a real number so you do not have to do anything.

Yes. Every number is a real number. Rational numbers, irrational numbers, Whole numbers, Natural numbers, integers are all real numbers.

No. There are several real numbers that are not rational (e.g. pi). However, every rational number is also a real number. In general, whole numbers/natural numbers is a subset of the integers (i.e. every whole number is an integer), the integers is a subset of the rationals, the rationals are a subset of the real numbers. I think the real numbers are a subset of the complex numbers, but I'm not 100% positive on that.

No, most real numbers are not whole numbers.

yes, only numbers like pi and e are irrational numbers

No, 1 is a factor of every whole number because 1 is a factor of every whole number.

It is a real number, but it is not a whole number

All whole numbers are rational.
