5/9 is a rational number because 5 and 9 are whole. Notice that every integer m is a rational number since mm /1. In mathematics, numbers are of different types - Natural Numbers, Whole Numbers, Integers, Real Numbers, Rational Numbers, Irrational Numbers, and Complex Numbers. Rational numbers are numbers that can be expressed as a fraction where the top and bottom are integers. 5/9 is not whole and it is certainly not negative so we dont need to even consider if is the opposite of a whole number.

It's not known whether C and aleph-one are the same or not, and if they're not, we don't know which is bigger. Integers are whole numbers plus the opposite of the whole numbers. There are also an infinite number of irrational numbers, but it's a "bigger" kind of infinity called C or the "power of the continuum." There's a relationship between aleph-null and a larger infinity called aleph-one. The mathematical designation for the kind of infinity that the integers have is called aleph-null. There are an infinite number of integers, and therefore an infinite number of rational numbers, but the two infinities are of the same order of magnitude (called a countable or listable infinity). If the number does not need a decimal or fraction. However, the sets of real numbers, imaginary numbers, and complex. Integers are natural numbers including 0 and negative signs of all. If it is already in fraction form, check if it simplifies to a non-fraction. The set of natural numbers and the set of rational numbers have the same cardinality as Z. Natural numbers are an ordered set of numbers that are used for counting and start from 1.
Irrational numbers are those that cannot be represented exactly by the ratio of two integers some familiar irrational numbers are pi and the square root of 2. Step 1: Determine if the number has a decimal or fraction part. In easiest way we can say Real Number is collection of Natural numbers, Whole numbers, Integers, Rational numbers, Irrational numbers, Prime numbers.
Rational numbers are those that are representable as the ratio of two integers: 2/3, 355/113, 5 (=5/1). If the decimal form of the number is terminating or recurring as in the case of 5.6 or 2. There are more irrational numbers between 0 and 1 than there are rational numbers period.I was kind of guessing what you were trying to ask, so let me explain some background in case that wasn't quite it. All integers, whole numbers, natural numbers, and fractions with integers are rational numbers. There are infinitely many rational numbers, but there are infinitely more irrational numbers than rational numbers. Are there rational numbers then irrational numbers?
