Rational+Numbers

=** Rational Numbers - A number that can be written in the form //a/b//, where //a// and //b// are integers and //b// is not equal to 0. Integers - The numbers ...., -3, -2, -1, 0, 1, 2, 3, 4, ....... and so on. **=

**A rational number is a number that can be expressed as a fraction or ratio. The numerator and the denominator of the fraction are both integers.** **When the fraction is divided out, it becomes a terminating or repeating decimal. (The repeating decimal portion may be one number or a billion numbers.) ** ** Rational numbers can be ordered on a number line. **


 * Both rational and irrational numbers are real numbers. **

the decimals will repeat after 41 digits ||
 * Examples:**
 * **6** or **6/1** || can also be written as || **6.0** ||
 * **-2 or -2/1** || can also be written as || **-2.0** ||
 * **1/2** || can also be written as || **0.5** ||
 * **-5/4** || can also be written as || **-1.25** ||
 * **2/3** || can also be written as || **0.666666666...** ||
 * **21/55** || can also be written as || **0.38181818...** ||
 * **53/83** || can also be written as || **0.62855421687...**
 * Be careful when using your calculator to determine if a decimal number is irrational. The calculator may not be displaying enough digits to show you the repeating decimals, as was seen in the last example above. ||
