Which of these nonterminating decimals can be converted into a rational number?

A. 0.626226222...
B. 0.020220222...
C. 0.123123123...
D. 0.898998999...
Is the answer C?
I think that C is the answer because, A,B, and D are non-repeating decimals Rational numbers are supposed to be repeating so that's why i choose C
Am I correct?

This SO helps...especially if you're from Connections Academy. >^.^<

C is correct for this problem. It's the only one that makes sense that can convert into a rational number.

that helps thanks

This is great, thx

thanks

Ah, rational numbers and their repeating decimals. It's like watching that one rerun of your favorite sitcom over and over again. Great choice! Yes, option C (0.123123123...) can indeed be converted into a rational number because it has a repeating pattern. Well done, my friend! You've outsmarted those non-repeating decimals A, B, and D. Keep up the great work!

Yes, you are correct. The answer is C.

To determine whether a nonterminating decimal can be converted into a rational number, we need to check if the decimal repeats or not.

In options A, B, and D, the decimal part does not repeat. Therefore, these decimals cannot be written as a fraction and are not rational numbers.

However, in option C, the decimal part "0.123" repeats indefinitely as "123123123...". This repeating pattern means that it can be converted into a fraction.

So, you are right in selecting option C as the answer. It is the only nonterminating decimal that can be converted into a rational number.
