stiks02 [169]
To answer this question let us first define what a rational and irrational number is. A rational number is basically a number whose decimals are terminating (ie have an end) or repeating (continuously repeats the same pattern. 

An example of this from your question would be 

5.3 - terminating rational number
5.333333333333..... - repeating rational number

Irrational numbers are basically numbers whose decimals are non terminating and non repeating. 

An example would be the square root of 29. When plugged in a calculator this would result in <span>5.3851648071..... 
</span>This number goes on and on with no set pattern.
