Yes 1.08 is a rational number because it can be expressed as a fraction
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
Yes. Any rational number divided by another rational number is also rational.
rational. Just remember that a rational number is one that may be formed from a ratio. e.g. -108/2.
No, the square root of negative 108 is not rational. The square root of a negative number involves imaginary numbers, specifically it can be expressed as ( \sqrt{-108} = \sqrt{108}i ), where ( i ) is the imaginary unit. Since rational numbers are defined as numbers that can be expressed as a fraction of two integers, and imaginary numbers cannot be represented in this way, the square root of negative 108 is not rational.
Yes.
It is a rational number. It can be written as a fraction.
yes
Is 12.05 a rational number or irrational number?
1.96 is a rational number
It is a rational number, as it can be written as a fraction.
Yes, the sum is always rational.
it is a composite number because 9x 12 = 108 and 1x 108 =108
There is no such thing as a number that is both rational and irrational. By definition, every number is either rational or irrational.
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.
