Real number, 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.
All rational numbers are real so the phrase "real rational" has no meaning. There are an infinite number of subsets: The emply or null set, {1,1.5, 7/3}, {2}, (0.1,0.2,0.3,0.66..., 5.142857142857...} are some examples.
There is no such number. The empty set is a subset of rational numbers and, by definition, it contains no numbers so nothing that can be common to any other subset.Alternatively, all rational numbers less than -1 and all rational numbers greater than 1 are subsets of rational numbers. There is no number common to them.
No, they are disjoint sets. Both are subsets of the Real numbers.
Integers, Rational numbers, Real numbers and Complex numbers.
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.
The one which says rational numbers (ℚ).
Rational.
An irrational number is a number that can't be expressed by a fraction having integers in both its numerator and denominator. A rational number can be.
The set of rational numbers. 23.8 can be expressed as the fraction 119/5
Any other rational number.
