SA2 Practice Paper - Mathematics Primary 5

Version 2 of 5 — ANSWER KEY

Section A: Multiple Choice Questions (20 marks)

[1 mark each]

1. Answer: C

Working:

Compare digits from left to right (highest place value first):

All numbers start with 7, so compare next digit.
A: 7 056 432 → 0 hundred thousands
B: 7 506 342 → 5 hundred thousands
C: 7 065 324 → 0 hundred thousands
D: 7 605 243 → 6 hundred thousands

Eliminate B and D (larger). Compare A and C:

A: 7 056 432 → 5 ten thousands
C: 7 065 324 → 6 ten thousands

Since 6 > 5, C is larger than A. Wait — we need the smallest: A) 7 056 432 has 5 ten thousands vs C) 7 065 324 has 6 ten thousands.

Re-checking: 7 056 432 vs 7 065 324. Both have 7 millions, 0 hundred thousands.

A: 5 ten thousands
C: 6 ten thousands

So A) 7 056 432 is smaller than C.

Wait — re-verify all:

A: 7 056 432
B: 7 506 342 ✗ (largest so far)
C: 7 065 324
D: 7 605 243 ✗ (largest so far)

Comparing A and C:

7 056 432 vs 7 065 324: 056 < 065, so A is smaller than C

Final check: C) 7 065 324 — no wait, let me be careful.

7 056 432: 7 million, 0 hundred-thousand, 5 ten-thousand, 6 thousand... 7 065 324: 7 million, 0 hundred-thousand, 6 ten-thousand, 5 thousand...

Position by position: millions equal (7), hundred-thousands equal (0), ten-thousands: 5 vs 6.

5 < 6, so 7 056 432 < 7 065 324.

Thus A < C. And A < B, A < D.

Final Answer: A) 7 056 432

2. Answer: A

Working:

In 9 840 517, identify place value of each digit:

Position	Digit	Value
Millions	9	9 000 000
Hundred thousands	8	800 000
Ten thousands	4	40 000
Thousands	0	0
Hundreds	5	500
Tens	1	10
Ones	7	7

The digit 4 is in the ten thousands place, so it stands for 4 ten thousands or 40 000.

Final Answer: A) 4 ten thousands

3. Answer: B

Working:

To round 3 456 789 to the nearest hundred thousand:

Identify the hundred thousands digit: 4 (in 3 456 789)
Look at the digit to its right (ten thousands place): 5
Rule: If this digit is 5 or more, round UP the hundred thousands digit

Since 5 ≥ 5, round 4 up to 5, and all digits to the right become 0.

3 456 789 → 3 500 000

Final Answer: B) 3 500 000

4. Answer: C

Working:

Break down 5 060 004 by place value:

Place	Digit	Value
Millions	5	5 000 000
Hundred thousands	0	0
Ten thousands	6	60 000
Thousands	0	0
Hundreds	0	0
Tens	0	0
Ones	4	4

So: 5 000 000 + 60 000 + 4 = 5 million 60 thousand 4

Final Answer: C) 5 million 60 thousand 4

5. Answer: A

Working:

Break down 8 003 020:

Place	Digit	Value
Millions	8	8 000 000
Hundred thousands	0	0
Ten thousands	0	0
Thousands	3	3 000
Hundreds	0	0
Tens	2	20
Ones	0	0

So: 8 000 000 + 3 000 + 20 = eight million three thousand and twenty

Final Answer: A) eight million three thousand and twenty

6. Answer: C

Working:

In 2 745 608, identify the place value of 7:

Position	Digit
Millions	2
Hundred thousands	7
Ten thousands	4
Thousands	5
Hundreds	6
Tens	0
Ones	8

The digit 7 is in the hundred thousands place.

Value = 7 × 100 000 = 700 000

Final Answer: C) 700 000

7. Answer: A

Working:

Add step by step:

4 000 000 + 300 000 = 4 300 000
4 300 000 + 5 000 = 4 305 000
4 305 000 + 60 = 4 305 060
4 305 060 + 8 = 4 305 068

Final Answer: A) 4 305 068

8. Answer: B

Working:

100 000 more than 5 678 901:

5 678 901 + 100 000 = 5 778 901

(Adding 1 to the hundred thousands digit: 6 → 7)

Final Answer: B) 5 778 901

9. Answer: C

Working:

8086 × 500

Method: 8086 × 5 × 100 = 40 430 × 100 = 4 043 000

Or: 8086 × 500 = 8086 × 5 × 100

8086 × 5:

8000 × 5 = 40 000
80 × 5 = 400
6 × 5 = 30
Total: 40 430

40 430 × 100 = 4 043 000

Final Answer: C) 4 043 000

10. Answer: B

Working:

Number ÷ 40 = 2505

So Number = 2505 × 40

2505 × 40 = 2505 × 4 × 10 = 10 020 × 10 = 100 200

Check: 100 200 ÷ 40 = 2505 ✓

Final Answer: B) 100 200

Section B: Short-Answer Questions (30 marks)

11. [1 mark]

Answer: Six million five hundred eight thousand and thirty-two

Working:

Break down 6 508 032:

6 000 000 = six million
500 000 = five hundred thousand
8 000 = eight thousand
30 = thirty
2 = two

Combine: "six million five hundred eight thousand and thirty-two"

Note: Use "and" before the tens/ones part in British English convention.

12. [2 marks]

Answer: 4 058 312, 4 085 132, 4 085 312, 4 805 312

Working: [1 mark for correct order, 1 mark for all correct]

Compare digit by digit from left:

Number	Millions	Hundred thousands	Ten thousands	...
4 058 312	4	0	5	...
4 085 132	4	0	8	...
4 085 312	4	0	8	...
4 805 312	4	8	0	...

First: Compare hundred thousands place:

4 805 312 has 8 (largest) → last

Rest have 0: compare ten thousands:

4 058 312 has 5 → smallest
4 085 132 and 4 085 312 both have 8: compare thousands
- 4 085 132 has 1 (thousand)
- 4 085 312 has 3 (thousand)

So: 4 085 132 < 4 085 312

Ascending order: 4 058 312 < 4 085 132 < 4 085 312 < 4 805 312

13. [2 marks]

Answer: 8 753 210

Working: [1 mark for using all digits, 1 mark for correct arrangement]

To form the greatest number, arrange digits in descending order from left to right:

Digits given: 5, 0, 3, 8, 2, 7, 1

Descending order: 8, 7, 5, 3, 2, 1, 0

Greatest number: 8 753 210

Note: 0 cannot be first (would make it a 6-digit number), but since we have a non-zero digit (8) for the highest place, this is valid.

14. [2 marks]

Answer: 288 000

Working: [1 mark for correct method, 1 mark for correct answer]

7200 × 40

Method 1: 7200 × 4 × 10 = 28 800 × 10 = 288 000

Method 2: 72 × 4 = 288, then add three zeros (from 7200) + one zero (from 40) = 288 000

15. [2 marks]

Answer: 3060

Working: [1 mark for correct method, 1 mark for correct answer]

2 448 000 ÷ 800

Method: Simplify by dividing both by 100 = 24 480 ÷ 8

24 480 ÷ 8:

24 000 ÷ 8 = 3 000
480 ÷ 8 = 60
Total: 3 060

Or: 2 448 000 ÷ 800 = 2 448 000 ÷ (8 × 100) = (2 448 000 ÷ 100) ÷ 8 = 24 480 ÷ 8 = 3 060

16. [3 marks]

Given information from diagram:

Number format: 4 _ 7 _ 2 1 _

(a) Answer: 7 [1 mark]

Working:

Digit in ten thousands place = 7
Digit in hundred thousands place is 10 times this value = 7 × 10 = 70... wait, that's a digit.

Re-reading: "The value of the digit in the hundred thousands place is 10 times the value of the digit in the ten thousands place."

Value in ten thousands place = 7 × 10 000 = 70 000

Value in hundred thousands place = 10 × 70 000 = 700 000

So digit in hundred thousands place = 700 000 ÷ 100 000 = 7

(b) Answer: 1 [1 mark]

Working:

Digit in hundreds place = 2
Digit in ones place = half of 2 = 1

Actually: 4 (millions), 7 (hundred thousands), 7 (ten thousands)? No, ten thousands is given as 7.

Reconstructing: 4 (millions), 7 (hundred thousands), 7 (ten thousands — given)... but we said hundred thousands = 7, and ten thousands = 7? That gives 4 77_21_.

Wait — let me re-read: "The value of the digit in the hundred thousands place is 10 times the value of the digit in the ten thousands place."

Ten thousands place has digit 7. Its value is 7 × 10 000 = 70 000.

Hundred thousands place value = 10 × 70 000 = 700 000.

So hundred thousands digit = 700 000 ÷ 100 000 = 7.

So number so far: 4 7 7 2 1 _

And ones place = half of hundreds digit = ½ × 2 = 1

Final number: 4 772 211 [1 mark]

17. [3 marks]

Answer: 39 000 bottles

Working: [1 mark for daily production, 1 mark for method, 1 mark for answer]

Step 1: Find daily production 15 600 ÷ 6 = 2 600 bottles per day

Step 2: Find 15-day production 2 600 × 15 = 39 000 bottles

Or combined: 15 600 ÷ 6 × 15 = 2 600 × 15 = 39 000

18. [4 marks]

(a) Answer: 1200 cookies [2 marks]

Working: 25 boxes × 48 cookies per box

25 × 48:

25 × 40 = 1000
25 × 8 = 200
Total: 1200 cookies

(b) Answer: 100 packets [2 marks]

Working: 1200 cookies ÷ 12 cookies per packet

1200 ÷ 12 = 100 packets

Or: 1200 ÷ 12 = (1200 ÷ 4) ÷ 3 = 300 ÷ 3 = 100

Section C: Word Problems (30 marks)

19. [7 marks]

(a) Labelling: [2 marks — 0.5 mark each correct label]

Expected positions on number line:

D at 1 250 000 (between 0 and 2 500 000)
A at 3 750 000 (between 2 500 000 and 5 000 000)
B at 6 250 000 (between 5 000 000 and 7 500 000)
C at 8 750 000 (between 7 500 000 and 10 000 000)

(b) Answer: 2 500 000 more coins [2 marks]

Working: 8 750 000 − 6 250 000 = 2 500 000

Working: [1 mark for total, 1 mark for method, 1 mark for answer]

Step 1: Find total coins 3 750 000 + 6 250 000 + 8 750 000 + 1 250 000 = 20 000 000

Step 2: Divide equally 20 000 000 ÷ 4 = 5 000 000 coins each

20. [8 marks]

(a) Answer: 1 230 000 packets [2 marks]

Working: [1 mark for method, 1 mark for answer]

April sales = February sales + 245 000 = 985 000 + 245 000 = 1 230 000

(b) Answer: 4 939 000 packets [3 marks]

Working: [1 mark for adding all four months, 1 mark for correct values, 1 mark for answer]

January: 1 256 000 February: 985 000 March: 1 468 000 April: 1 230 000

Total = 1 256 000 + 985 000 + 1 468 000 + 1 230 000

= (1 256 000 + 985 000) + (1 468 000 + 1 230 000) = 2 241 000 + 2 698 000 = 4 939 000 packets

Working: [1 mark for method, 1 mark for subtraction, 1 mark for answer]

Remaining = Original − Sold = 5 800 000 − 4 939 000 = 861 000 packets

21. [7 marks]

(a) Answer: $3 680 000 [2 marks]

Working: [1 mark for method, 1 mark for answer]

Flat B + Flat C = Flat A + $1 230 000 =$ 2 450 000 + $1 230 000 = **$ 3 680 000**

(b) Answer: $2 275 000 [3 marks]

Working: [1 mark for setting up, 1 mark for finding half difference, 1 mark for answer]

Given: Flat C = Flat B − $870 000

So: Flat B + (Flat B − $870 000) =$ 3 680 000 2 × Flat B − $870 000 =$ 3 680 000 2 × Flat B = $3 680 000 +$ 870 000 = $4 550 000 Flat B =$ 4 550 000 ÷ 2 = $2 275 000

Completed Table:

Equation	Product
456 × 7 =	3192
456 × 70 =	31 920
456 × 700 =	319 200
456 × 700 =	319 200
4560 × 700 =	3 192 000

Marking:

456 × 70 = 31 920 [1 mark] — multiply 3192 by 10 (one zero in 70)
456 × 700 = 319 200 [1 mark] — multiply 3192 by 100 (two zeros in 700)
Missing multiplier: 456 [1 mark] — 319 200 ÷ 700 = 456, or recognize 319 200 is 100 × 3192 so need 456 × 700
4560 × 700 = 3 192 000 [2 marks — 1 mark for method, 1 mark for answer]

Pattern recognition:

456 × 70: 70 = 7 × 10, so product = 3192 × 10 = 31 920
456 × 700: 700 = 7 × 100, so product = 3192 × 100 = 319 200
? × 700 = 319 200: Since 319 200 = 3192 × 100 = 456 × 7 × 100 = 456 × 700, answer is 456
4560 × 700: 4560 = 456 × 10, so 4560 × 700 = 456 × 10 × 7 × 100 = 456 × 7 × 1000 = 3192 × 1000 = 3 192 000

Or: 4560 × 700 = (456 × 700) × 10 = 319 200 × 10 = 3 192 000
