I assume you mean "repeating decimal". Yes. For example, 1/6 = 0.166666... after that, the digit "6" repeats over and over again. In other cases, it is more than one digit that repeats, over and over. Note that at first there may be other digits, that don't repeat later on.
In general, any fraction (with integers on top and bottom), if converted into a decimal, will eventually start repeating. Conversely, any repeating decimal can be converted into a fraction.

It is a rational number and expressed as a fraction it is 2/9
Any decimal that can't be expressed as a fraction is an irrational number
Yes, 6.35 repeating (often written as 6.35̅) is a rational number. A rational number is defined as any number that can be expressed as a fraction of two integers. In this case, 6.35 repeating can be represented as a fraction, making it rational.
