Answer:
Never
Step-by-step explanation:
A Rational Number is a number of the form [tex]\frac{p}{q}[/tex], p & q are integers and q ≠ 0.
An irrational number is all real number except rational numbers i.e. it is a non-repeating and non-terminating decimal number or it can not be expressed in a ratio of two integers.
Further, Natural numbers can be a rational number.
Also, all repeating and terminating decimals are rational.
The difference of rational number and irrational number is never a rational number. For example:
2 - √3 is always an irrational number where 2 is rational and √3 is an irrational number.
Hence addition and subtraction of rational and irrational number is never a rational number it will be irrational number always.
