A decimal number which has finite number of digits after the decimal is called Recurring decimals.
Example: 0.35
A decimal where decimal representation becomes periodic or same sequence of digits keeps repeating indefinitely is called terminating decimals.

Comparing decimals

Any two decimal numbers can be compared by comparing their whole part and decimal parts.
If the whole parts are equal then the tenth parts can be compared and so on.

Example-
Compare 22.3 and 22.5
As Whole parts are equal; hence we compare tenths part.
$\begin{array}{l}22.3 = 22{\rm{ }} + {\rm{ }}\dfrac{3}{{10}}\\22.5{\rm{ }} = {\rm{ }}22{\rm{ }} + {\rm{ }}\dfrac{5}{{10}}\\\dfrac{3}{{10}} < \dfrac{5}{{10}}\\\therefore 22.3{\rm{ }} < {\rm{ }}22.5.\end{array}$
