What examples represents a repeating decimal A. 1.111114 B. 0.123123 C. 0.777777 D. 4.252525?

Answer 1

There can be no proper answer to this question. First. all the number given in the question terminate after six decimal places and so none are repeating.

If these are meant to be numbers represented by longer strings, it is not possible to tell what the longer strings are. For example, A could be 1.11111444... or 1.1111141414... or 1.111114114... etc, in each case with the underlined string repeating. Or A could be a non-terminating, non-repeating number such as sqrt(1.23457433).
