1, 3, 5, 7, 9
It is rational but not an integer.
It can be greater than, equal or less than the original integer. There are three possible values for the second integer: It is positive, in which case the result will be less than the original integer, eg 5 - 2 = 3 and 3 < 5;It is zero, in which case the result will be the same as the original integer, eg 5 - 0 = 5 and 5 = 5;It is negative, in which case the result will be greater than the original integer, eg 5 - -2 = 7 and 7 > 5.
An integer can be written as a fraction. 7 = 7/1 or 21/3 but in its simplified form it is not a fraction.
Yes a rational number is one which can be represented by one integer over another (possibly the same) integer which cannot be zero. 1 2/7 = (1×7+2)/7 = 9/7 (as an improper fraction) 9/7 is one integer over another integer, so it is a rational number.
+7
The integer "-8" is less than "-7".
1 < 4N + 7 < 200 Subtract 7: -6 < 4N < 193 Divide by 4: -1.5 < N < 48.25 Since N is an integer, it can take all integer values from -1 to 48 inclusive, that is 50 of them.
Any integer greater than 7.
-5
1, 3, 5, 7, 9
a = b + 7; 2a = b2 - 1. Substituting: 2b + 14 = b2 - 1 or b2 - 2b - 15 = 0 Factors are (x - 5)(x + 3) b = 5, a = 12. Also works with b = -3 and a = 4

In order of greatness they are: -1 -3 -5 and -7
