I assume you mean 15 recurring indefinitely. This would be 0.15 x (1 + 0.01 + 0.0001 +....) The thing in brackets is an infinite geometric series with ratio 0.01 and the summation to infinity of that is 1/(1-0.01) or 1/0.99. So you finish up with 0.15/0.99 which is 15/99 or 5/33 . For things with a single digit repetition like 0.22222... you would use the series (1 + 0.1 + 0.01 .....) which is 1/(1-0.1) or 10/9 so you would get 0.2 x 10/9 which is 2/9 .
It is a repeating decimal.
4/11 is a repeating decimal.
The latter which would be an irrational number that cannot be expressed as a fraction.
Any rational number is either a repeating decimal, or a terminating decimal.
No, the sum of a repeating decimal and a terminating decimal is never a terminating decimal.
It is a repeating decimal.
0.875 is a terminating decimal and as a fraction it is 7/8
If the decimal is terminating or repeating then it can be written as a fraction. Decimal representations which are non-terminating and non-repeating cannot be expressed as a fraction.

A negative fraction need not be a terminating decimal. For example, -2/3 = -0.66... (repeating).
Any rational number is either a repeating decimal, or a terminating decimal.
No, the sum of a repeating decimal and a terminating decimal is never a terminating decimal.
It is terminating - after two decimal digits.
0.2 a repeating decimal into a fraction = 2/9
To sum this answer up you half to turn the fraction into a decimal and if it ends that is terminating but if it keeps going it is called a repeating decimal EXAMPLES Terminating- 5/10=.5 Repeating- 1/3=.3333 (bar notation over the 3)
