Why 5/125 is not a irrational number.
To understand this we must know the characterstics of a Rational Number.
A rational number is one which can be written in the form of p/q where q is a non zero integer.
In this Case,
the number 5/125 can also be written in the form of p/q where p=5 and q=125
Understanding in another way also.
A rational number is one which decimal expansion is terminating or non terminating repeating.
In this case,
5/125 = 0.2
Here the decimal expansion is terminating showing that 5/125 is a rational number.
And if 1/125 is a rational number it can't be a irrational number.
Hence, Explained
