Yes, because ALL integers are rational numbers.
Yes.
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."
All integers are rational numbers.
No.
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.

'3' is RATIONAL. All numbers are RATIONAL except those were the decimal goes to infinity AND the decimal digits are NOT in any regular order. pi = 3.1419592.... is probably the most well known IRRATIONAL number. Also the Square Roots of Prime numbers. NB 3.333.... recurring to infinity is RATIONAL, because it can be converted to a RATIO/Fraction.
A rational number which is an integer can be simplified to a form in which the denominator is 1. That is not possible for a rational number which is not an integer.
