TuitionGoWhere Practice Paper - Mathematics Primary 4 - Answer Key

SA2 (Version 3 of 5)

Section A: Multiple Choice (10 marks)

Qn	Answer	Marks	Working / Explanation
1	D	2	In 63 814, the digit 3 is in the thousands place. Value = 3 × 1 000 = 3 000. Common mistake: Confusing "digit" (3) with "value" (3 000).
2	C	2	45 726: The digit in the hundreds place is 7. Since 7 ≥ 5, round up. 45 726 ≈ 46 000.
3	B	2	18 ÷ 4 = 4 R2 (No). 24 ÷ 3 = 8, 24 ÷ 4 = 6 (Yes). 27 ÷ 4 = 6 R3 (No). 32 ÷ 3 = 10 R2 (No).
4	B	2	Division before addition: 84 ÷ 6 = 14. Then 14 + 15 = 29. Common mistake: Calculating left-to-right (84 ÷ 21 = 4).
5	C	2	Rounding to nearest hundred: 8 349 → 8 300. 8 395 → 8 400. 8 449 → 8 400. 8 460 → 8 500. Both 8 395 and 8 449 round to 8 400. Only C is an option.
6	A	2	8 × 25 = 200. 200 – 45 = 155.
7	C	2	Multiples of 4: 4, 8, 12, 16, 20, 24... Multiples of 6: 6, 12, 18, 24... First two common multiples: 12 and 24. Sum = 12 + 24 = 36.
8	C	2	Using distributive law: 6 × 40 + 6 × 8 = 6 × (40 + 8) = 6 × 48 = 288. Or: 240 + 48 = 288.
9	C	2	1 250 × 6 = 7 500.
10	D	2	9 450 ÷ 9 = 1 050.

---

Section B: Short Answer (20 marks)

Qn	Answer	Marks	Working / Explanation
11	42 005	2	Forty-two thousand = 42 000. Five = 5. Combine: 42 005.
12	32 804, 38 024, 38 204	2	Compare ten-thousands (3), then thousands (2 vs 8). 32 804 is smallest. Then compare hundreds: 0 vs 2. 38 024 < 38 204.
13	952	2	136 × 7 = 952.
14	Quotient: 709, Remainder: 6	2	5 678 ÷ 8: 8 × 709 = 5 672. 5 678 – 5 672 = 6.
15	84	2	Division before subtraction: 64 ÷ 8 = 8. Then 92 – 8 = 84. Common mistake: Left-to-right (92 – 64 = 28, 28 ÷ 8 = 3.5).
16	1, 2, 3, 4, 6, 9, 12, 18, 36	2	Find pairs: 1×36, 2×18, 3×12, 4×9, 6×6. List in order.
17	80	2	Multiples of 5: 5, 10, 15... 50, 55, 60, 65, 70, 75, 80... Multiples of 8: 8, 16, 24... 40, 48, 56, 64, 72, 80... First common multiple > 50 is 80.
18	50 000	2	Original: 57 293. New: 52 293. Difference = 57 293 – 52 293 = 5 000. Or: The digit 7 is in the ten thousands place (70 000). Replaced by 2 (20 000). Difference = 70 000 – 20 000 = 50 000.
19	29 500	2	29 504: The digit in the tens place is 0. Since 0 < 5, round down. 29 504 ≈ 29 500.
20	3 830	2	15 000 – 6 780 = 8 220. 8 220 – 4 390 = 3 830.
