No, they are disjoint sets. Both are subsets of the Real numbers.

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.

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.

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.

There are an infinite number of subsets: {1, 3/4} is one subset, {-3, 2.6666..., 1/2} is another, all integers is yet another.

Rational.

The one which says rational numbers (ℚ).

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.

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.

The number 0.444444 is a rational number. It is equivalent to 111111/250000, which, by definition of rational numbers, is rational. The number 0.444... (repeating) is also rational because it can be represented by the fraction 4/9. The number 0.444444 is a rational number because a rational number is a nnumber that can be expressed in the form of a fraction.

The rational numbers are a subset of the real numbers. You might recall that rational numbers are those that can be expressed as the ratio of two whole numbers (no matter how large they are). Irrational numbers, like pi, cannot. But both sets (the rational and irrational numbers) are subsets of the real numbers. In fact, when we look at all the numbers, we are looking at the complex number system. We break that down into the real and the imaginary numbers. And the real numbers have the rational and irrational numbers as subsets. It's just that simple.

Any other rational number.

A fraction is a number, it is not a set. A number cannot have subsets, only a set can.

The number of elements. A set with n elements has 2n subsets; for example, a set with 5 elements has 25 = 32 subsets.

9.0 is a rational number

It is a rational number.

It is a rational number

It is a rational number. It can be written as a fraction.

If the set is of finite order, that is, it has a finite number of elements, n, then the number of subsets is 2n.

If the set has n elements, the number of subsets (the power set) has 2n members.

If the set has "n" elements, then you can make 2n different subsets. The number of subsets will always be greater than the size of the set, both for finite and for infinite sets.
