Answer:

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.
