Question

Which describes a number that cannot be irrational?

Answer 1

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
