They form a proper subset of rational numbers.
If the decimal stops or repeats, it can be written as a fraction. If it goes on randomly forever, it can't.
1/7 (the fraction) then it's 0.142857, and the 142857 in the fraction part repeats forever.

repeating decimal
It means that it is a decimal representation of a rational fraction.
If the decimal stops or repeats, it can be written as a fraction. If it goes on randomly forever, it can't.
17 is already in decimal. If you mean 1/7 (the fraction) then it's 0.142857, and the 142857 in the fraction part repeats forever.
0.1888 (repeats) is equivalent to the fraction 17/90.
891/1250 if you cut the repeats down
If the 7 repeats forever, it's 7/9 .
The decimal of the fraction 8 over 110 is 0.07272. The 72 in the decimal repeats itself indefinitely, as in 0.072727272...
1/7 (the fraction) then it's 0.142857, and the 142857 in the fraction part repeats forever.

The answer depends on the repeating string and also on other digits after the decimal point before the repeating string starts.
It is not possible to have a terminating decimal which repeats or a repeating decimal which terminates. The two types are mutually exclusive.
