No.
Yes, -3 is both a rational number and an integer.
-16 is both a negative integer and a rational number
By definition, an irrational number is a number that is not rational, or in other words a number that cannot be expressed as an integer divided by another integer. A number cannot be both "rational" and "not rational."
Integers are whole numbers, with no fraction or decimal part. Rational numbers are numbers that can be expressed in the form a/b where a and b are both integers. Thus 1/2 is a rational number, but not an integer. 0.34343434... is a rational number (as it can be expressed as 34/99) but is not an integer.
All integers are rational numbers.
An integer is a whole number. For instance, 1, 2, 3... There is no decimal part. So 23 is an integer. A rational number is a number that can be written as a/b. 23 can be written as 23/1, so 23 is a rational number. Thus, 23 is BOTH an integer and a rational number.
Yes, -3 is both a rational number and an integer.
It can be both.
-16 is both a negative integer and a rational number
Every integer is.
Yes and yes. It is an integer and so it is also a rational number.

both
The number 3 is a rational number (as is any integer).
