Statement 1 is true but totally unnecessary. As integer is always a rational and you do not need to convert it to a fraction to determine whether or not it is rational. A negative fraction is can be rational or irrational. The fact that it is negative is irrelevant to its rationality. An integer number over a zero denominator is not defined and so cannot be rational or irrational or anything. It just isn't.
TrueYes.All rational numbers are a fraction of one integer (numerator) over another integer (denominator).All integers can be made into a[n improper] fraction over a denominator of 1.Thus all integers are rational numbers
Rational yes, integer no.
-42 is rational. All integers are rational numbers as they can be expressed as the number over 1 which, being one integer over another integer, is the form of a rational number.
Yes. A rational number is one which can be expressed as one integer over another integer. 656.95 = 65695/100000 which is of the form of one integer over another one; thus it is a rational number.

Yes, any integer over any other integer (except zero) is always a rational number.
Rational yes, integer no.
No. To be a rational number it must be an integer over another integer. π is not an integer, nor can it be made into an integer by multiplying it by another integer, thus one twelfth of π is not a rational number.
Every integer can be expressed as a ratio of itself over 1. Also, any rational number that has a numerator that is divisible by the denominator is an integer. BUT all rational numbers are not integers.
0 is an integer and not a fraction. However, it can be expressed in rational form as 0/1. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any positive integer. But whatever number you choose, the numerator will always be 0 so the equivalent fraction is 0/k for any integer non-zero k.
A rational number is one which can be expressed as one integer over another (possibly the same) integer which is not zero. thirty thirds = 30/3 which is one integer over another integer → it is rational.

A rational number is one that can be expressed as one integer (whole number) over another integer. 4.89 = 489 ÷ 100 = 489/100 In this form 489 is an integer and 100 is an integer, so 4.89 can be expressed as one integer over another integer, thus it is a rational number.
