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.
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
Yes.
Yes, but only if the rational number is 0.
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 rational number.
ANY number that has a finite number of decimal digits is RATIONAL.
Rational. A rational number, z, is any number that can represented in the formx/y = z

No, it is not.
Yes, it does.
9.3 is a rational number, as it can be expressed as a fraction.
When a rational numbers is divided by an irrational number, the answer is irrational for every non-zero rational number.

7.6 is a rational number. Any number that can be expressed as a/b is rational.
Yes, all whole numbers (integers) are rational. Please note though that not all rational numbers are integers.
