Bust out a calculator and divide them.

When it has a bar over it, that means that the one continues. So the actual decimal is 0.11111111111. To find the answer, divide all the rational numbers. I'll do A for example.
A. 1/11 (1 divided by 11) which is .09090909. It's close, but not the answer. Now, try the others.

♪chibiterasu · Answer

The actual decimal is impossible to write out as it is infinite, so it is represented with a bar on top of the repeating value.
