Section A: Multiple Choice (15 marks)

1. (A) - 8 is in hundred thousands place = 800 thousands
2. (B) - 6,789,324 rounds to 6,800,000
3. (A) - 20 - 8 ÷ 4 + 6 = 20 - 2 + 6 = 24
4. (B) - 5/8 = 15/24
5. (B) - 3/4 + 5/12 = 9/12 + 5/12 = 14/12 = 1 2/12 = 1 1/6
6. (A) - 2 1/2 × 1 3/5 = 5/2 × 8/5 = 40/10 = 4
7. (B) - 60% of 85 = 0.6 × 85 = 51
8. (B) - 1 pen = $3, so 15 pens =$45
9. (C) - 4.2 × 1000 = 4200
10. (A) - Area = 1/2 × 18 × 7 = 63 cm²
11. (B) - Straight angle = 180°
12. (B) - 7/10 = 70%
13. (B) - 4/5 of 30 = 24
14. (B) - Speed = 180 ÷ 4 = 45 km/h
15. (B) - Perimeter = 2(16 + 9) = 50 cm

Section B: Short Answer (20 marks)

16. Eight million, two hundred and nine thousand, four hundred and seventy-five 17. a) 960 ÷ 10 × 100 = 9600 b) 0.84 × 1000 = 840 18. a) 36/48 = 3/4 b) 28/42 = 2/3 19. a) 4 2/3 - 1 5/6 = 14/3 - 11/6 = 28/6 - 11/6 = 17/6 = 2 5/6 b) 3/5 × 20 = 12 20. a) 80% of 65 = 52 b) 27/108 = 25% 21. Speed = 420 ÷ 3 = 140 km/h. Distance in 5 hours = 140 × 5 = 700 km

Section C: Word Problems (25 marks)

22. Toys remaining = 18,567 - 9,834 = 8,733. Need to produce = 4,725 - 8,733 = 0 (already have enough). Actually need to produce = 4,725 toys for new order. 23. Total spent = 1/4 + 3/8 = 2/8 + 3/8 = 5/8. Left = 3/8 × $48 =$18 24. If 3/7 = 156, then total = 364 students. Girls = 4/7 × 364 = 208 25. Discount = 25% of $80 =$20. Sale price = $60 26. Distance = 12 × 1.75 = 21 km. Time for 30km = 30 ÷ 12 = 2.5 hours
