🔷 CHAPTER 1: FRACTIONS
Q1. Which of the following is a proper fraction?
A. 7/4 B. 9/5 C. 5/5 D. 3/8 ← CORRECT E. 11/3
RATIONALE: A proper fraction has a numerator smaller than the denominator. 3/8
meets this criterion since 3 < 8.
Q2. Which of the following is an improper fraction?
A. 2/9 B. 1/4 C. 3/7 D. 5/11 E. 13/4 ← CORRECT
RATIONALE: An improper fraction has a numerator equal to or greater than the
denominator. 13/4 qualifies since 13 > 4.
Q3. Convert 3 2/5 to an improper fraction.
A. 5/3 B. 12/5 C. 14/3 D. 17/5 ← CORRECT E. 15/3
RATIONALE: Multiply the whole number (3) by the denominator (5) = 15, then add the
numerator (2) = 17. Place over the denominator: 17/5.
,Q4. Convert 22/7 to a mixed number.
A. 2 1/7 B. 2 5/7 C. 3 1/7 D. 3 1/7 ← CORRECT E. 4 2/7
RATIONALE: Divide 22 ÷ 7 = 3 remainder 1. The mixed number is 3 1/7.
Q5. Reduce 18/24 to its lowest terms.
A. 9/12 B. 6/8 C. 3/4 ← CORRECT D. 2/3 E. 4/5
RATIONALE: The GCF of 18 and 24 is 6. Dividing both by 6: 18/6 = 3, 24/6 = 4.
Result: 3/4.
Q6. What is 1/4 + 2/4?
A. 2/8 B. 3/8 C. 3/4 ← CORRECT D. 1/2 E. 4/8
RATIONALE: When denominators are the same, add numerators: 1 + 2 = 3. Keep
denominator: 3/4.
Q7. What is 1/3 + 1/6?
A. 2/9 B. 2/6 C. 1/2 ← CORRECT D. 2/3 E. 3/6
RATIONALE: LCD of 3 and 6 is 6. Convert 1/3 to 2/6. Then 2/6 + 1/6 = 3/6 = 1/2.
Q8. What is 5/8 − 1/4?
A. 4/4 B. 1/2 C. 3/8 ← CORRECT D. 4/8 E. 2/8
RATIONALE: LCD is 8. Convert 1/4 to 2/8. Then 5/8 − 2/8 = 3/8.
, Q9. What is 3/5 × 2/3?
A. 5/8 B. 1/3 C. 2/5 ← CORRECT D. 6/8 E. 3/5
RATIONALE: Multiply numerators: 3 × 2 = 6. Multiply denominators: 5 × 3 = 15.
Simplify 6/15 = 2/5.
Q10. What is 3/4 ÷ 1/2?
A. 3/8 B. 1/2 C. 1 D. 3/2 ← CORRECT E. 2/3
RATIONALE: Dividing by a fraction means multiplying by its reciprocal. 3/4 × 2/1 = 6/4
= 3/2.
Q11. Which fraction is the largest?
A. 1/6 B. 1/4 C. 1/3 D. 1/2 ← CORRECT E. 1/8
RATIONALE: For fractions with the same numerator, the smallest denominator yields
the largest value. 1/2 has the smallest denominator.
Q12. What is the LCD of 1/4 and 1/6?
A. 8 B. 10 C. 12 ← CORRECT D. 24 E. 4
RATIONALE: The LCD of 4 and 6 is the smallest number divisible by both, which is
12.
Q13. Reduce 36/48 to lowest terms.
A. 18/24 B. 9/12 C. 3/4 ← CORRECT D. 2/3 E. 6/8
RATIONALE: GCF of 36 and 48 is 12. 36 ÷ 12 = 3; 48 ÷ 12 = 4. Result: 3/4.
