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.
