Answer:
127 is rational number.
Step-by-step explanation:
The given number 127 is rational because it can be written as the quotient of two integers (p and q) like shown below:
[tex] \frac {p} {q} [/tex] which can be represented as [tex] \frac {127} {1} [/tex]
But if it is the square root of the same number [tex]\sqrt{127}[/tex], then it would be an irrational number since the square root of 127 would gives a decimal number that will keep going on and cannot be represented as a fraction.
