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.
