Terminating Decimals
• A decimal that comes to an endExamples:1.340.5678453213.4565

• A decimal that repeats one of more digits infinitely.

The line on top of the number(s) is called bar notation. It means to repeat that block of number(s).

• A decimal that terminates or repeats can be written as a fraction and thus is a Rational Number

When the same block of digits in a decimal repeats without end, that is called a repeating decimal.
