Answer: Option 4 is correct.

Step-by-step explanation:

Since we have given that

[tex]\dfrac{3.\bar{1}}{1}[/tex]

so, Let x = 3.1111......... (1)

Now, multiply by 10, we get that

10x = 31.1111.............(2)

Now, subtract (2)-(1)

[tex]10x-x=31.1111...-3.1111............\\\\9x=28\\\\x=\dfrac{28}{9}[/tex]

Hence, Option 4 is correct.
