Whole numbers : 0,1,2,3,4,... Integers : Whole numbers and negative whole numbers : ...,-4,-3,-2,-1,0,1,2,3,4,... Rational numbers : Numbers defined as ratios of integers : 1/2, 5/6, 8/3,... When x=-1 1/2 is a rational number When x=0 -1/3 is a rational number When x=1 1 is a rational number (1/1), an integer, and a whole number
