Answer
Natural numbers: N/A
Integers: -1
Rational numbers: -1, -1.1, -1.2, -1.3
Irrational numbers: N/A
Real numbers: -1, -1.1, -1.2, -1.3
Work Step by Step
Natural numbers: Are positive whole numbers (greater than zero). None of the numbers satisfy this criterion.
Integers: Are whole numbers that can be positive, negative or zero. -1 satisfies this criterion.
Rational numbers: Are numbers that can be made into a fraction with integers. All of the numbers satisfy this criterion.
Irrational numbers: Are numbers that cannot be made into a fraction with integers. None of the numbers satisfy this criterion.
Real numbers: Are numbers that can exist on the number line. All of the numbers satisfy this criterion.
