-3 is a rational number, whole number and an integer. Here's why:
Natural numbers are positive whole numbers (17, 973, 6109, etc). Since it's -3, it is not a natural number.
Rational numbers are any number (positive, negative, fractions, or *decimals). *The exceptions are the following 4 irrational numbers: Pi, Euler's Number (e), the square root of 2, and the square root of 3. Thus meaning -3 is a rational number.
Whole numbers fall into the same category as natural numbers. Whole numbers are non-fraction, positive or negative numbers. -3 is negative, so it qualifies as a whole number.
Integers are any whole number (positive or negative). -3 is a negative whole number, thus meaning it is an integer.
I hope this helps!
