Objectives Vocabulary Example 1 Example 2 Quick Quiz • To explore the relationship between number sets • To use Venn diagrams to represent number sets • To compare and order rational numbers • To place rational numbers on a number line • natural numbers • rational numbers • whole numbers A. Identify all sets to which the number 15 belongs. Answer: 15 is a whole number, an integer, and a rational number. Rational Numbers B. Answer: . C. Identify all sets to which the number 0.30303030… belongs. Answer: 0.30303030… is a nonterminating, repeating decimal. So, it is a rational number. A. Identify all sets to which –7 belongs.
