Answer:
A number that cannot be irrational is:
A number that cannot be written as the ratio of two integers
Step-by-step explanation:
Irrational numbers can be defined as those numbers which cannot be written as in a form of Fraction (Ration of two integers).
E.g if we consider the value of constant pi
π = 3.14159265...................
and it goes on, that why we cannot write it in a form of simple fraction.
Another example of irrational number is under root of 2
√2 = 1.41421356..................
Hence, it also cannot be written as a simple fraction.
However, a number which can be written as a ratio of two integers is a rational number. e.g
2/5 , 1/4 etc
As a rational number can never be an irration number, so statement 1 is correct
