Answer:
A
Step-by-step explanation:
Since all of the answer choices are non-terminating decimals, to find which is rational, we will have to see which is a repeating decimal. Repeating decimals have repeating sets of numbers, such as in the number:
0.33333333333333333333333333333333...
which can be written as the fraction 1/3.
All repeating decimals are rational because they can always be rewritten as a fraction.
From looking carefully at the answer choices, we can see that answer choice A is a repeating decimal, and therefore, is rational. Therefore, answer choice A is the correct answer.
I hope you find my answer and explanation to be helpful. Happy studying.
