8
1, 3, 5, 7, 9
It is rational but not an integer.
The integer 49 is a composite number because it has divisors other than 1 and itself. Specifically, it can be expressed as (7 \times 7), meaning it is the square of the prime number 7. Therefore, 49 has divisors of 1, 7, and 49.
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.
+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

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.
