4. What is the least common multiple (LCM) of 8 and 12?
A) 12
B) 16
C) 24
D) 48
Answer C: 24
Rationale: Multiples of 8: 8, 16, 24. Multiples of 12: 12, 24. The smallest common
multiple is 24.
5. Which of the following fractions is equivalent to 0.625?
A) 3/5
,B) 5/8
C) 2/3
D) 7/11
Answer B: 5/8
Rationale: 5 ÷ 8 = 0.625.

A) 50
B) 70
C) 80
D) 100
Answer B: 70
Rationale: 0.35 × 200 = 70.

of sugar, how many cups of flour are needed?
A) 4
B) 6
C) 8
D) 10
Answer B: 6
Rationale: Ratio flour/sugar = 2/3 = x/9 → x = 6.
, 8. What is the value of 4³?
A) 16
B) 32
C) 64
D) 128
Answer C: 64
Rationale: 4 × 4 × 4 = 64.

A) 1/2
B) 3/8
C) 1.5 or 3/2
D) 2/3
Answer C: 1.5 or 3/2
Rationale: Dividing by a fraction is the same as multiplying by its reciprocal: 3/4 ×
2/1 = 6/4 = 3/2.
