No.
Select any non-zero integer D and let N = -173*D.Then the quotient N/D = -173*D/D = -173.
Yes, as long as the two nonzero numbers are themselves rational. (Since a rational number is any number that can be expressed as the quotient of two rational numbers, or any number that can be written as a fraction using only rational numbers.) If one of the nonzero numbers is not rational, the quotient will most likely be irrational.
An integer is any whole number.
138 is, itself, an integer. It is impossible for any integer to lie between two consecutive integers.
The definition of a rational number is the quotient of any two nonzero integers.
That is because that is how the product and quotient are defined.
Any integer divided by a non-zero integer is rational.
True.
Yes, it is.
yes
No.
It follows from the definitions of the two operations.
It is true, and it follows from the definition of multiplication and division.
1 is the least common factor of any set of positive integers because 1 is a factor of all nonzero integers and 1 is the smallest positive integer.
No. The second integer MUST be non-zero.
an integer is any whole number for example 1, -1, 72, -72 the quotient is the answer to a division problem so the quotient of 2 integers is one whole number divided by another whole number
