If you consider terminating decimals as ones that end in repeating 0s, then the answer is "always".
Always
A number with a finite number of decimal digits is always rational. (If the number of decimal digits is infinite, the number is rational only if there is a repeating pattern.)
Sometimes. The number '4' is real and rational. The number 'pi' is real but not rational.
All repeating decimals are rational numbers. Not all rational numbers are repeating decimals.
always!
Repeating decimals are always rational.

Yes.
Yes.
A rational number always repeats or terminates which can be thought of as repeating zeroes.

Is 0.88 repeating a rational number
It is a rational number.
The square of a rational number can be either rational or irrational. However, the square of an irrational number is always irrational.
All repeating decimals are rational numbers. Not all rational numbers are repeating decimals.
