Is a repeating decimal a rational number? A- No, because it cannot be written in the form a/b, where a and b are integers and b≠0.

B- No, because it cannot be written in the form a • b, where a and b are integers.

C- Yes, because it can be written in the form a/b, where a and b are integers and b ≠ 0.

D- Yes because it can be written in the form a • b, where a and b are integers.
