Yes.
It is rational. An irrational number is a number that you cannot define by a fraction or a decimal. Since you wrote it as a decimal, it is rational. The fact that it is negative does not matter.
Is 12.05 a rational number or irrational number?
1.96 is a rational number
There is no such thing as a number that is both rational and irrational. By definition, every number is either rational or irrational.
275 is an integer and not a fraction. However, it can be expressed in rational form as 275/1. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.

It is a rational number. It can be written as a fraction.
2.75 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. Its equivalent, in rational form, is 275/100. You can simplify this rational fraction if required.

It is a rational number, as it can be written as a fraction.
Yes, the sum is always rational.

275% = 2.75
As much as, in these days of uncertainty, anything can be anything. As long as the constraints of a rational number are kept to, a rational number will always remain a rational number.
25% of a number equates to 25/100 of that number. 25% of 275 = 275 x 25/100 = 68.75 A 25% decrease in 275 = 275 - 68.75 = 206.25
