Answer:
Any number that can be written as a fraction with integers is called a rational number .
For example, 17 and −34 are rational numbers.
(Note that there is more than one way to write the same rational number as a ratio of integers. For example, 17 and 214 represent the same rational number.)
All integers are rational numbers.
The number −8 is a rational number because it can be rewritten as −81 .
The number 0 is a rational number because it can be rewritten as 01 .
All mixed numbers are rational numbers.
315 is a rational number because it can be re-written as 165 .
All decimals which either terminate or have a repeating pattern after some point are also rational numbers.
The number 0.2 is a rational number because it can be re-written as 15 .
The number 0.33333… is a rational number because it can be re-written as 13 .
Some numbers can't be rewritten as a fraction with integers, and so they are not rational numbers. Some examples are π and the square root of any prime number. These are called irrational numbers.
