no: the decimal is not repeating or terminating and therefore cannot be written as a fraction, which is one of the two requirements to be a rational number.
yes
Yes.

It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.
Yes
Sadly, it is not. It is the ratio of -51 to 1. That simple operation demonstrates that your number is quite rational.
Any integer (whole number) is RATIONAL.
Because it can be expressed in the form of a ratio of two integers: -51 and 1.
It can be a rational number or an irrational number. For example, sqrt(2)*sqrt(50) = 10 is rational. sqrt(2)*sqrt(51) = sqrt(102) is irrational.

It is a rational number. It can be written as a fraction.

Is 12.05 a rational number or irrational number?
-4172 = -4172/1, 5.1= 51/10Both can be expressed as a ratio of two integers and so are rational.
1.96 is a rational number
It is a rational number, as it can be written as a fraction.
