  4.  36 is what kind of number? Practice 2 (subsets of real numbers) A Real/ Irrational B Real/rational/integer/ whole/natural C Real/rational/integer/whole D Real/rational

  5. Which of the following is a rational number? Practice 3 (subsets of real numbers) A 3 B  C 1/5 D 25/115

  7. Ordering Real Numbers • Real numbers are ordered from least to greatest. • Example: 1, -4, 49, -16/2, 19/5 ordered from least to greatest would be: -16/2 (-8), -4, 1, 49, (7), 19/5 (3.8)

  8. Practice 5 (ordering real numbers) • Order the following numbers from smallest to largest: -8, 14/3, 10, 5 A -8, 14/3, 10, 5 B -8, 5, 14/3, 10 C -8, 10, 5, 14/3 D -8, 14/3, 5, 10

  9. Practice 6 (ordering real numbers) • Order the following numbers from least to greatest: 144, -47, 19/6, -13 A -47, -13, 19/6, 144 B -47, -13, 144, 19/6 C -13, -47, 144, 19/6 D -47, 144, 19/6, -13
