Answer 2

B.
`0.4166\overline{6}`,
`√(81)`,
`(1)/(8)`.

Explanation:

We are asked to find the list that contains only rational numbers.

We know that a number is known as rational, when it can be expressed as a fraction.

Upon looking at our given choices, we can see that option B is the correct choice.

In
`0.4166\overline{6}`, the digit 6 has a bar on it, this means that it is repeating. We know that a repeating decimal is a rational number.

`√(81)=9`. We can represent 9 as a fraction:
`(9)/(1)`.

`(1)/(8)` is already written as a fraction, therefore, it is a rational number.
