Answer 2

$\frac{1}{0}$ is not a rational number.

So, option D is the correct answer.

Step-by-step explanation:

Given, four numbers are $( - \frac{4}{5} )$,$( - \frac{3}{7} )$,$\frac{0}{5}$,$\frac{1}{0}$

We want to find the number which is not a rational numbers.

But now question is what is rational number?

We know,

$\frac{p}{q}$ is a rational number where p and integers and q is not equal to zero.

We are doing option test,

Option -A:

Here the number is $( - \frac{4}{5} )$

$( - \frac{4}{5} )$ is form of $\frac{p}{q}$

Where p= -4 and q=5 which is not equal to zero.

So,$( - \frac{4}{5} )$ is a rational number.

Option -B:

Here the number is $( - \frac{3}{7} )$

$( - \frac{3}{7} )$ is form of $\frac{p}{q}$

where p = -3 and q = 7 which is not equal to zero.

So,

$( - \frac{3}{7} )$ is a rational number.

Option -C:

$\frac{0}{5}$ is form of $\frac{p}{q}$ where p = 0 and q = 5 which is not equal to zero.

So,

$\frac{0}{5}$ is a rational number.

Option - D:

$\frac{1}{0}$ is form of $\frac{p}{q}$ where p = 1 and q = 0

So it is clear that

$\frac{1}{0}$ is not a rational number.

Therefore, option - D is correct answer.
