A rational number
The fraction 12/18 can be simplified to 2/3 by dividing both the numerator and denominator by their greatest common divisor, which is 6. Since the fraction 2/3 can be expressed as a ratio of two integers and can be written in the form a/b where a and b are integers and b is not equal to 0, it is considered a rational number. Rational numbers are numbers that can be expressed as a ratio of two integers.
It is probably a mixed rational number.
Irrational numbers. A good example of this is pi. If you were to write out pi as a decimal, the digits after the decimal point would go on forever.
Prime numbers are integers. They won't equal a decimal.
rational numbers
Irrational numbers, such as √2 or π, cannot be written as a fraction pq where p and q are integers and q is not equal to zero. These numbers cannot be expressed as a ratio of two integers and are non-repeating and non-terminating decimals.
It is the set of rational numbers.
All integers are rational numbers, not all rational numbers are integers. Rational numbers can be expressed as fractions, p/q, where q is not equal to zero. For integers the denominator is 1. 5 is an integer, 2/3 is a fraction, both are rational.

Any rational number.
A rational number.
In mathematics, a rational number is any number that can be expressed as the quotient or fraction a/b of two integers, with the denominator b not equal to zero. Since all whole numbers are integers, all fractions made up of whole numbers will be rational.
