Section A: Multiple Choice (20 marks)

2 marks each

1. B) 60 thousand

   • The digit 6 is in the ten thousands place
   • 6 × 10,000 = 60,000

2. B) 4,660,000

   • Look at the thousands digit: 7
   • Since 7 ≥ 5, round up the ten thousands place

3. A) 11

   • Using BODMAS: 2 + 6 × 3 ÷ 2 = 2 + 18 ÷ 2 = 2 + 9 = 11

4. B) 6/9

   • 2/3 = (2×3)/(3×3) = 6/9

5. B) 7/8

   • Common denominator = 8
   • 3/4 = 6/8, so 6/8 + 1/8 = 7/8

6. C) 3/4

   • 0.75 = 75/100 = 3/4 (divide by 25)

7. C) 36

   • 3.6 × 10: Move decimal point 1 place right

8. D) 0.564

   • Compare digit by digit: 0.564 is largest

9. B) 45°

   • Angle sum in triangle = 180°
   • Third angle = 180° - 45° - 90° = 45°

10. C) 96 cm²

    • Area = length × width = 12 × 8 = 96 cm²
