Good luck! MULTI CHOICE QUESTIONS 1. Which of the following is a natural number? A) -3 B) 0 C) 5 D) ½ Correct Answer: C Rationale: Natural numbers are the counting numbers: 1, 2, 3, 4, ... Thus, 5 is a natural number. -3 is an integer but not natural, 0 is a whole number but not natural (in most definitions), and ½ is a rational number but not an integer. ________________________________________ 2. The set of all numbers that can be expressed as a ratio of two integers, where the denominator is not zero, is called: A) Natural numbers B) Integers C) Rational numbers D) Irrational numbers Correct Answer: C Rationale: By definition, rational numbers are numbers that can be written in the form p/q where p and q are integers and q ≠ 0. Natural numbers and integers are subsets of rational numbers, while irrational numbers cannot be expressed as a ratio of integers. ________________________________________ 3. Which property is illustrated by: 3 + (5 + 2) = (3 + 5) + 2 A) Commutative Property of Addition B) Associative Property of Addition C) Distributive Property D) Identity Property of Addition Correct Answer: B Rationale: The associative property states that the way in which numbers are grouped when adding does not change the sum: a + (b + c) = (a + b) + c. The commutative property involves changing order (a + b = b + a), while the distributive property involves multiplication over addition. ________________________________________ 4. The additive inverse of -7 is: A) 7 B) -7 C) 1/7 D) 0 Correct Answer: A Rationale: The additive inverse of a number is the number that, when added to the original, gives zero. For -7, the additive inverse is 7 because -7 + 7 = 0. ________________________________________ 5. Which number is irrational? A) √4 B) 0.75 C) π D) -8 Correct Answer: C Rationale: An irrational number cannot be expressed as a ratio of two integers. π (pi) is irrational. √4 = 2 (rational), 0.75 = 3/4 (rational), and -8 is an integer (rational). ________________________________________
