Answer Key
Section A: Short Answer (1 mark each)
1. 48 × 25 = 1,200
Working: 48 × 25 = 48 × (100 ÷ 4) = 4,800 ÷ 4 = 1,200
2. 672 ÷ 8 = 84
Working: 672 ÷ 8 = (640 + 32) ÷ 8 = 80 + 4 = 84
3. 305 × 46 = 14,030
Working:
305
× 46
-----
1830 (305 × 6)
12200 (305 × 40)

5. 9,000 ÷ 12 = 750
Working: 9,000 ÷ 12 = (9,000 ÷ 6) ÷ 2 = 1,500 ÷ 2 = 750
6. 1,001 × 78 = 78,078
Working: 1,001 × 78 = (1,000 × 78) + (1 × 78) = 78,000 + 78 = 78,078
7. Boxes: 41 Leftover: 16
Working: 1,000 ÷ 24 = 41 remainder 16 24 × 41 = 984; 1,000 − 984 = 16
8. 156 × 101 = 15,756
Working: 156 × 101 = (156 × 100) + (156 × 1) = 15,600 + 156 = 15,756

Marking: 1 mark for correct method, 1 mark for correct answer.
13. 480 × 1.75 = 840 pages (or 480 × 7/4 = 840)
Working: 1 hour 45 minutes = 1.75 hours = 7/4 hours 480 × 7 ÷ 4 = 3,360 ÷ 4 = 840
Alternative: 480 × 1 = 480; 480 × 3/4 = 360; 480 + 360 = 840
Marking: 1 mark for converting time correctly, 1 mark for final answer.
14. 999 × 45 = 44,955
Working: 999 × 45 = (1,000 − 1) × 45 = 45,000 − 45 = 44,955
Marking: 1 mark for correct method using (1000 − 1), 1 mark for correct answer.
15.
(a) 2,016 ÷ 24 = 84 mangoes per crate
Working: 2,016 ÷ 24 = (2,016 ÷ 8) ÷ 3 = 252 ÷ 3 = 84
(b) 84 × 2,940**
Working: 84 × 35 = (84 × 30) + (84 × 5) = 2,520 + 420 = 2,940

Section C: Problem Sums (3 marks each)
16.
(a) 25 × 48 = 1,200 chairs
Working: 25 × 48 = 25 × 4 × 12 = 100 × 12 = 1,200
(b) 1,200 < 1,350, so there are not enough chairs. 1,350 − 1,200 = 150 more chairs needed.
Marking: 1 mark for (a) correct answer. 1 mark for comparison/statement. 1 mark for correct number of additional chairs.
17.
(a) 1,650 × 8 = 13,200 bottles
Working: 1,650 × 8 = (1,600 × 8) + (50 × 8) = 12,800 + 400 = 13,200
(b) 13,200 ÷ 24 = 550 full cartons, remainder 0 bottles
Working: 13,200 ÷ 24 = (13,200 ÷ 12) ÷ 2 = 1,100 ÷ 2 = 550
Marking: 1 mark for (a). 1 mark for correct division. 1 mark for correct number of cartons and remainder.
