Question

Which list contains ONLY rational numbers?

Answer 1

Answer:

B. $0.4166\overline{6}$, $\sqrt{81}$, $\frac{1}{8}$.

Step-by-step 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.

$\sqrt{81}=9$. We can represent 9 as a fraction: $\frac{9}{1}$.

$\frac{1}{8}$ is already written as a fraction, therefore, it is a rational number.
