1. A repeating decimal is a decimal number that eventually takes on a repeating pattern of digits after its decimal point that will continue forever. For example, 17.(23)=17.23232323232323....
2. A decimal number that has digits that do not go on forever is called terminating decimal. Any rational number (that is, a fraction in lowest terms) can be written as either a terminating decimal or a repeating decimal . Just divide the numerator by the denominator . If you end up with a remainder of 0, then you have a terminating decimal. Otherwise, the remainders will begin to repeat after some point, and you have a repeating decimal.
3. Repeating decimal between 0 and 1: 0.(987)=0.987987987987...
Terminating number between 0 and 1: 0.987
0.(987) >0.987.
4. When dividing 1 by 6 you can get 0.1666666666...=0.1(6).
