Rational numbers are, by definition, expressible that way.
The definition of an irrational number is that it cannot be expressed as the quotient of 2 integers, so no.
Every whole number can be expressed as the quotient or ratio of other whole numbers, and whole numbers ARE integers.
A quotient of two numbers cannot have a denominator which is zero: such a fraction is not defined.

Yes, negative 0.75 is a rational number. A rational number is defined as any number that can be expressed as the quotient of two integers, where the denominator is not zero. Negative 0.75 can be expressed as -3/4, which fits this definition.

A rational number is one such that it is "capable of being expressed as an integer or a quotient of integers, excluding zero as a denominator." So you must ask yourself: can 2.25 be expressed as a quotient of integers? In other words, can you divide one integer by another and get 2.25? The answer is yes, because 9 divided by 4 is 2.25. Therefore, 2.25 is a rational number.
