Natural numbers consist of any positive number which does not have fractional parts. This set does not include zero. 1, 2, 3, 4, 5, 6, 7, … Fractions Mixed Numbers Negative Numbers

Whole numbers consist of any positive number which does not have fractional parts. This set includes zero. 0, 1, 2, 3, 4, 5, 6, 7, … Fractions Mixed Numbers Negative Numbers

Integers are whole numbers both positive and negative. This set also includes zero. …, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, … Fractions Mixed Numbers Negative Numbers

Rational numbers include all integers as well as terminating & repeating decimals, fractions, and mixed number. …, -3, -2. 75, -2, -1, 0, ½, . 7, 1, 2, 3, 3. 5 … Fractions Mixed Numbers Negative Numbers
