250 is an integer and not a fraction. However, it can be expressed in decimal form as 250 and in rational form as 250/1. You can also calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.
Incidentally, a decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. Adding zeros after the decimal point is wrong because they imply a degree of accuracy (significant figures) for which there is no justification.
-1.716 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, since it is a decimal fraction, there is not another simpler decimal form. Its equivalent, in rational form, is -1716/1000 which simplifies to -429/250.
0.036 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, since it is a decimal fraction, there is not another simpler decimal form. Its equivalent, in rational form, is 36/1000 which simplifies to 9/250.
