  1. B) 70 thousand

    • The digit 7 is in the ten thousands place
  2. A) 6,300,000

    • Look at hundreds thousands: 6,329,847 → 6,300,000
  3. A) 5

    • Order of operations: 15 - 3 × 4 + 2 = 15 - 12 + 2 = 5
  4. B) 9/15

    • 3/5 = 3×3/5×3 = 9/15
  5. D) 11/12

    • 2/3 + 1/4 = 8/12 + 3/12 = 11/12
  6. C) 5/8

    • 0.625 = 625/1000 = 5/8 (simplest form)
  7. C) 230

    • 2.3 × 100 = 230
  8. C) 0.279

    • Compare: 0.279 is smallest
  9. A) 45°

    • Third angle = 180° - 38° - 97° = 45°
  10. C) 49 cm²

    • Area of square = side² = 7² = 49 cm²

Section B: Short Answer (30 marks)

  1. Seven million, two hundred and nine thousand, four hundred and fifty-six [2 marks]

  2. Ascending order: [2 marks] 3,275,186 < 3,725,861 < 3,752,681 < 3,757,268

  3. 32,400 [3 marks] Working: 3,240 ÷ 100 = 32.4 32.4 × 1,000 = 32,400

  4. Simplified fractions: [4 marks] a) 15/25 = 3/5 b) 18/24 = 3/4

  5. 4 1/12 [4 marks] Working: 2 1/3 + 1 3/4 = 2 4/12 + 1 9/12 = 3 13/12 = 4 1/12

  7. Rounding 6.789: [3 marks] a) 1 decimal place = 6.8 b) 2 decimal places = 6.79

  8. Missing angles: [4 marks] a) Angle R = 180° - 72° - 53° = 55° b) Missing angle = 360° - 95° - 110° - 80° = 75°

  9. Rectangle calculations: [5 marks]

    • Perimeter = 2(11 + 6) = 34 cm
    • Area = 11 × 6 = 66 cm²

Section C: Word Problems (20 marks)

  1. Larger number = 7,542 [4 marks] Working: 4,695 + 2,847 = 7,542

  2. Total fraction = 13/20 [4 marks] Working: 2/5 + 1/4 = 8/20 + 5/20 = 13/20

  3. Total cost = $40.70 [6 marks] Working:

    • Rice: 4 × 6.80=6.80 = 27.20
    • Oil: 3 × 4.50=4.50 = 13.50
    • Total: 27.20+27.20 + 13.50 = $40.70
  4. Playground calculations: [6 marks] a) Area = 18² = 324 m² b) Perimeter = 4 × 18 = 72 m Cost = 72 × 12=12 = **864**
