Detailed Solution

We are given a number as 22 7 .
We have to identify if 22 7 is an irrational number and accordingly decide if the statement is true or not.
A rational number is the one which can be expressed as a fraction or as a ratio of two integers say p q , where p and q are integers and q is non-zero.
So, we clearly say that 22 7 is a fraction where the numerator i.e., 22 and the denominator i.e., 7 are integers and 7 is non-zero.
Thus, by definition, 227 is a rational number, and this contradicts the given statement.
Hence, the statement is false.
So, the correct option is 2.
