It is rational and also a whole number.
Yes.
Given any two integers, x and y, such that y is not 0, then x/y is a rational number. So for example, 3476/43 is a rational number.
It is not defined, so it is not a number of any kind.
0.43 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 rational equivalent is 43/100 which cannot be simplified.

It is a decimal with 2 significant figures. It is a rational number 4.3 = (43/10). Not sure what else you're looking for.
It belongs to any set that contains it! For example, {-1.576}, or {45, sqrt(2), pi, -3/7, -1.576}, or numbers between -43 and 53, or rational numbers, or real numbers, or negative rational numbers, etc One set in particular that includes -1.576 is the set of rational numbers (ℚ).
