proper order of operations?
A) 25
B) 46
C) 67
D) 99
Correct Answer: C. 67
Using PEMDAS: First evaluate inside parentheses (6-3)=3, then exponent 3²=9,
then multiplication 7×9=63, then addition 4+63=67 .
Q4. Given the following expression: 5 × (30 – 27)² + 4. What is the correct
answer using the proper order of operations?
A) 34
B) 49
C) 65
D) 81
Correct Answer: B. 49
,Using PEMDAS: First (30-27)=3, then 3²=9, then 5×9=45, then 45+4=49 .
Q5. 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: D. 11
The square root of 121 is 11. The prime factorization of 132 is 2² × 3 × 11. Both
132 and 11 share the factor 11, making 11 the GCF .
Q6. What is the greatest common factor of 24 and 84 using prime factorization?
A) 2
B) 4
C) 8
D) 12
Correct Answer: D. 12
Prime factorization: 24 = 2³ × 3, 84 = 2² × 3 × 7. The common factors are 2² × 3 =
12 .
, Q7. What is 3/14 – 1/7?
A) 1/14
B) 2/7
C) 5/14
D) 3/2
Correct Answer: A. 1/14
Find common denominator (14): 1/7 = 2/14. 3/14 – 2/14 = 1/14 .
