P4 Maths Quiz: Fractions - Answer Key

Questions: 20
Time: 30 minutes
Total Marks: 40

Section A: Multiple Choice Questions (10 marks)

1. Which fraction is equivalent to 3/4? (2 marks)

Answer: (3) 9/12

Explanation: 3/4 = (3×3)/(4×3) = 9/12

  • Check: 9 ÷ 12 = 0.75 and 3 ÷ 4 = 0.75 ✓

2. Which fraction is in its simplest form? (2 marks)

Answer: (2) 3/8

Explanation: 3/8 cannot be simplified further (GCD of 3 and 8 is 1)

  • 6/9 = 2/3, 4/12 = 1/3, 10/15 = 2/3 (all can be simplified)

3. What is 1/2 + 1/4? (2 marks)

Answer: (4) 3/4

Explanation:

  • Find common denominator: LCM(2,4) = 4
  • 1/2 = 2/4
  • 2/4 + 1/4 = 3/4

4. Which fraction is the largest? (2 marks)

Answer: (1) 7/8

Explanation: Convert to common denominator 24:

  • 7/8 = 21/24
  • 2/3 = 16/24
  • 3/4 = 18/24
  • 5/6 = 20/24
  • 21/24 is largest

5. What is 5/6 - 1/3? (2 marks)

Answer: (3) 1/2

Explanation:

  • Find common denominator: LCM(6,3) = 6
  • 1/3 = 2/6
  • 5/6 - 2/6 = 3/6 = 1/2

Section B: Short Answer Questions (15 marks)

6. Express these fractions in their simplest form: (3 marks)

(a) 8/12 Answer: 2/3 Working: GCD(8,12) = 4, so 8/12 = (8÷4)/(12÷4) = 2/3

(b) 15/20
Answer: 3/4 Working: GCD(15,20) = 5, so 15/20 = (15÷5)/(20÷5) = 3/4

(c) 18/24 Answer: 3/4 Working: GCD(18,24) = 6, so 18/24 = (18÷6)/(24÷6) = 3/4

7. Add these fractions: (3 marks)

(a) 1/5 + 2/5 Answer: 3/5 Working: Same denominator: 1/5 + 2/5 = 3/5

(b) 1/3 + 1/6 Answer: 1/2 Working: LCM(3,6) = 6, so 1/3 = 2/6, then 2/6 + 1/6 = 3/6 = 1/2

(c) 2/5 + 1/10 Answer: 1/2 Working: LCM(5,10) = 10, so 2/5 = 4/10, then 4/10 + 1/10 = 5/10 = 1/2

8. Subtract these fractions: (3 marks)

(a) 4/7 - 1/7 Answer: 3/7 Working: Same denominator: 4/7 - 1/7 = 3/7

(b) 3/4 - 1/2 Answer: 1/4 Working: LCM(4,2) = 4, so 1/2 = 2/4, then 3/4 - 2/4 = 1/4

(c) 5/6 - 1/4 Answer: 7/12 Working: LCM(6,4) = 12, so 5/6 = 10/12 and 1/4 = 3/12, then 10/12 - 3/12 = 7/12

9. Convert these mixed numbers to improper fractions: (3 marks)

(a) 2 1/3 Answer: 7/3 Working: 2 1/3 = (2×3+1)/3 = 7/3

(b) 3 2/5 Answer: 17/5 Working: 3 2/5 = (3×5+2)/5 = 17/5

(c) 1 3/4 Answer: 7/4 Working: 1 3/4 = (1×4+3)/4 = 7/4

10. Convert these improper fractions to mixed numbers: (3 marks)

(a) 11/4 Answer: 2 3/4 Working: 11 ÷ 4 = 2 remainder 3, so 11/4 = 2 3/4

(b) 19/6 Answer: 3 1/6
Working: 19 ÷ 6 = 3 remainder 1, so 19/6 = 3 1/6

(c) 23/8 Answer: 2 7/8 Working: 23 ÷ 8 = 2 remainder 7, so 23/8 = 2 7/8

Section C: Word Problems (15 marks)

11. Sarah ate 1/4 of a pizza. Her brother ate 2/8 of the same pizza. What fraction of the pizza did they eat altogether? (3 marks)

  • He gave away: 1/3
  • Find common denominator: LCM(4,3) = 12
  • 3/4 = 9/12, 1/3 = 4/12
  • Amount left: 9/12 - 4/12 = 5/12

Answer: 5/12 of the chocolate bar

13. A recipe needs 2 1/2 cups of flour. Mei Ling has 1 3/4 cups of flour. How much more flour does she need? (4 marks)

Working:
