The fact that they can be expressed as a ratio of two whole numbers (with the denominator being non-zero).
Some definitions maintain that the set of whole numbers does not include negative numbers. That makes -12 an integer and rational.
Terminating numbers are decimal representations of rational numbers. Nonterminating numbers may or may not be rational numbers.
Some rational numbers are whole numbers, some are not. The set of whole numbers is a proper subset of rational numbers.
There are infinitely many rational numbers between any two consecutive rational numbers. This is because rational numbers can be expressed as fractions, and between any two fractions, an infinite number of other fractions can be found by taking the average of the two given fractions. Therefore, the set of rational numbers is dense, meaning there is no smallest gap between any two rational numbers.
all rational numbers can be written as fractions. That is the definition of rational numbers.
The question cannot be answered sensibly because it is based on a lack of understanding of rational numbers. Some rational numbers ARE whole numbers and so the question makes no sense.
The question makes no sense because rational numbers are not necessarily whole numbers: only an infinitesimally tiny proportion are.
Yes.2 and 0.5 are both rational. But 2^0.5, which is sqrt(2), is irrational.
All numbers can make a square. Every real number makes a positive real square. Every rational number makes a rational square. Every integer makes a perfect square.
If there are no numbers after the 9 it is rational
All whole numbers are rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
No. Rational numbers are numbers that can be written as a fraction. All rational numbers are real.
The set of rational numbers includes all whole numbers, so SOME rational numbers will also be whole number. But not all rational numbers are whole numbers. So, as a rule, no, rational numbers are not whole numbers.
An irrational number is a number that has no definite end. 4.5 has a definite end. THis makes it a rational number.
Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. All natural numbers are rational.
6.6 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
The set of rational numbers includes the set of natural numbers but they are not the same. All natural numbers are rational, not all rational numbers are natural.
