1. Given the following set of numbers: 3.3, -2.3, -16, 25. What are
the square roots of the whole number?
A) ±2.3
B) ±3.3
C) ±4
D) ±5 — CORRECT ANSWER
Rationale: The whole number in the set is 25. The square root of 25
is ±5. The square root of a positive number has both a positive and
negative root. -16 is an integer but not a whole number (whole
numbers are non-negative), and 3.3 and -2.3 are decimals. Therefore,
±5 is the correct answer.
,2. Given the following set of numbers: 10, 2.5, -4, -4.5, 5. What is the
sum when adding together only the whole numbers?
A) 5.5
B) 11
C) 12.5
D) 15 — CORRECT ANSWER
Rationale: Whole numbers are positive numbers including zero,
without fractions or decimals. In this set, the whole numbers are 10
and 5. -4 is an integer but negative, so it is not a whole number. 2.5
and -4.5 are decimals. Sum = 10 + 5 = 15.
3. Given the following expression: 4 + 7 × (6 − 3)². What is the
answer using proper order of operations?
A) 25
B) 46
,C) 67 — CORRECT ANSWER
D) 99
Rationale: Step 1: Parentheses: (6 − 3) = 3. Step 2: Exponent: 3² = 9.
Step 3: Multiplication: 7 × 9 = 63. Step 4: Addition: 4 + 63 = 67.
4. Given the following expression: 5 × (30 − 27)² + 4. What is the
correct answer using proper order of operations?
A) 34
B) 49 — CORRECT ANSWER
C) 65
D) 81
Rationale: Step 1: Parentheses: (30 − 27) = 3. Step 2: Exponent: 3² =
9. Step 3: Multiplication: 5 × 9 = 45. Step 4: Addition: 45 + 4 = 49.
, 5. What is the greatest common factor of 132 and the square root of
121 using prime factorization?
A) 1
B) 2
C) 10
D) 11 — CORRECT ANSWER
Rationale: The square root of 121 is 11. The prime factorization of
132 is 2² × 3 × 11. The prime factorization of 11 is 11. The greatest
common factor is 11.
6. What is the greatest common factor of 24 and 84 using prime
factorization?
A) 2
B) 4
