Yes, a rational number can be a repeating decimal. A repeating decimal is a decimal in which one or more digits repeat infinitely. For example, 1/3 is a rational number that can be written as the repeating decimal 0.333...
1/3 = 0.3333 repeating
2 over 3 is already a fraction number. This can be written as decimal as 0.667.
As written it is a terminating decimal. However, if the digits 123456789101112 keep on repeating after the amount written (normally it would be written with a dot over the first 1 and the last 2; as that is impossible here, to show repeating an ellipsis (three dots) could be used, as in: 0.123456789101112123456789101112... to show that it goes on) then it is a repeating decimal.
It is 1.888... (repeating).
