How are repeating decimals used?
If a non-zero rational number, in its simplest form, has a denominator with any factor other than 2 or 5, the ratio cannot be represented by a terminating decimal. So, repeating decimals are used to represent the vast majority of rational numbers.
Is 0.123456789101112123456789101112 a repeating decimal?
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.
