Answer:
The rational numbers are 
and the irrational functions are 
.
Step-by-step explanation:
A rational number can be expressed in the form of 
, where p and q are integers and q is not equal to 0. For example 
.
An irrational function can not be expressed in the form of , where p and q are integers and q is not equal to 0. For example 
.
If any number is multiplied by a irrational number then the resultant number is an irrational number.
By the above definition we can conclude that:
The number 
is a rational number.
Therefore 
is an irrational number.
Therefore 6.25 is a rational number.
Therefore 0.01045 is a rational number.
The number 
is a rational number.
The number 
is an irrational number.
Therefore 
is an irrational number. The numbers with recursive bar are always rational numbers.
