Paper: Practice Paper 1 (Version 1)
Total Marks: 50
SECTION A: Multiple-Choice Questions (10 marks)
1. Which of the following numbers is equal to 4 050 000? [2]
Answer: (3)
Explanation:
4 050 000 = 4 million + 50 thousand = 4 050 000.
Option (1) is 4 500 000 (4 million 500 thousand).
Option (2) is 4 005 000 (4 million 5 thousand).
Option (4) is 4 000 500 (4 million 500).
2. Round off 3 487 621 to the nearest ten thousand. [2]
Answer: (2)
Explanation:
To round to the nearest ten thousand, look at the thousands digit (7).
Since 7 ≥ 5, round up the ten thousands digit (8) to 9.
3 487 621 → 3 490 000.
3. What is the value of the digit 7 in 6 724 583? [2]
Answer: (2)
Explanation:
Place values from right: ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions.
The digit 7 is in the hundred thousands place.
Value = 7 × 100 000 = 700 000.
4. Find the value of 8 000 000 − 2 345 678. [2]
Answer: (1)
Working:
8 000 000
− 2 345 678
-----------
5 654 322
5. A factory produced 2 450 000 toys in January and 1 780 000 toys in February. How many more toys were produced in January than in February? [2]
Answer: (1) / (2) / (3) / (4) — All options are identical (670 000).
Working:
2 450 000 − 1 780 000 = 670 000
Note: This question has identical options. In a real paper, options would differ. The correct answer is 670 000.
SECTION B: Short-Answer Questions (20 marks)
6. Write 5 080 040 in words. [2]
Answer: Five million, eighty thousand and forty.
Marking:
- 1 mark for "Five million"
- 1 mark for "eighty thousand and forty" (accept "eighty thousand forty")
Common mistake: Writing "five million eight thousand forty" (missing the zero in ten thousands place).
7. In 9 304 567, which digit is in the hundred thousands place? [2]
Answer: 3
Explanation:
Place values: 9 (millions), 3 (hundred thousands), 0 (ten thousands), 4 (thousands), 5 (hundreds), 6 (tens), 7 (ones).
8. Arrange the following numbers from the smallest to the greatest. [2]
4 500 000, 4 050 000, 4 005 000, 4 000 500
Answer: 4 000 500, 4 005 000, 4 050 000, 4 500 000
Explanation:
Compare digit by digit from the left (millions place): all have 4 million.
Then compare hundred thousands: 0, 0, 0, 5 → 4 500 000 is greatest.
Then ten thousands: 0, 0, 5 → 4 050 000 is next.
Then thousands: 0, 5 → 4 005 000 is next.
Smallest is 4 000 500.
9. Find the value of 3 456 789 + 2 543 211. [2]
Answer: 6 000 000
Working:
3 456 789

6 000 000
10. Find the value of 7 000 000 − 4 567 890. [2]
Answer: 2 432 110
Working:
7 000 000
− 4 567 890
-----------
2 432 110
11. Multiply 4 567 by 300. [2]
Answer: 1 370 100
Working:
4 567 × 300 = 4 567 × 3 × 100 = 13 701 × 100 = 1 370 100
12. Divide 5 678 000 by 800. [2]
Answer: 7 097.5 or 7 097 remainder 400
Working:
5 678 000 ÷ 800 = 5 678 000 ÷ 8 ÷ 100 = 709 750 ÷ 100 = 7 097.5
Alternatively: 5 678 000 ÷ 800 = 7 097 remainder 400
13. Find the value of 24 × (500 + 300) − 12 000. [2]
Answer: 7 200
Working (Order of Operations - BODMAS):
Step 1: Brackets first: 500 + 300 = 800
Step 2: Multiplication: 24 × 800 = 19 200
Step 3: Subtraction: 19 200 − 12 000 = 7 200
14. A library has 3 450 000 books. 1 230 000 books are fiction. The rest are non-fiction. How many non-fiction books are there? [2]
Answer: 2 220 000

Answer: $4 919 755
Working:
Total spent = 2345678+1 234 567 = 3580245Moneyleft=8 500 000 − 3580245=4 919 755
SECTION C: Structured / Long-Answer Questions (20 marks)
16. A stadium has a seating capacity of 5 000 000. During a concert, 3 456 789 seats were occupied. [4]
(a) How many seats were empty? [2]
Answer: 1 543 211
Working:
5 000 000 − 3 456 789 = 1 543 211
(b) Express the number of empty seats to the nearest hundred thousand. [2]
Answer: 1 500 000
Working:
Empty seats = 1 543 211
Ten thousands digit = 4 (< 5), so round down.
1 543 211 ≈ 1 500 000 (nearest hundred thousand)
17. A company printed 2 500 000 calendars. They packed them into boxes of 400 calendars each. [4]
(a) How many boxes were needed? [2]
Answer: 6 250
Working:
2 500 000 ÷ 400 = 2 500 000 ÷ 4 ÷ 100 = 625 000 ÷ 100 = 6 250
**(b) If each box was sold for 120,howmuchmoneywascollectedfromsellingalltheboxes?∗∗[2]∗∗Answer:∗∗750 000
Working:
6 250 × 120=6250×12×10=75000×10=750 000
18. The population of Town A is 4 567 890. The population of Town B is 1 234 567 less than Town A. The population of Town C is twice the population of Town B. [4]
(a) What is the population of Town B? [2]
Answer: 3 333 323
Working:
Town B = 4 567 890 − 1 234 567 = 3 333 323
(b) What is the total population of the three towns? [2]
Answer: 11 234 536
Working:
Town C = 2 × 3 333 323 = 6 666 646
Total = 4 567 890 + 3 333 323 + 6 666 646 = 11 234 536
19. A factory produces 1 250 000 bottles of juice in 5 days, working the same number of hours each day. [4]
(a) How many bottles does it produce in one day? [2]
Answer: 250 000
Working:
1 250 000 ÷ 5 = 250 000
(b) At this rate, how many bottles will it produce in 30 days? [2]
Answer: 7 500 000
Working:
250 000 × 30 = 7 500 000
20. Study the number pattern below. [4]
4 000 000, 3 500 000, 3 000 000, 2 500 000, ______, ______
(a) What are the next two numbers in the pattern? [2]
Answer: 2 000 000, 1 500 000
Explanation:
The pattern decreases by 500 000 each time.
2 500 000 − 500 000 = 2 000 000
2 000 000 − 500 000 = 1 500 000
(b) What is the 10th number in the pattern? [2]
Answer: 500 000
Working:
1st term = 4 000 000
Common difference = −500 000
nth term = 4 000 000 + (n − 1)(−500 000)
10th term = 4 000 000 + 9(−500 000) = 4 000 000 − 4 500 000 = −500 000
Wait — let's check the pattern again:
1st: 4 000 000
2nd: 3 500 000
3rd: 3 000 000
4th: 2 500 000
5th: 2 000 000
6th: 1 500 000
7th: 1 000 000
8th: 500 000
9th: 0
10th: −500 000
Correction: The 10th number is −500 000 (negative five hundred thousand).
However, in Primary 5 context, negative numbers may not be expected. If the pattern stops at 0, the 10th term would be −500 000. Accept −500 000 or "negative 500 000" as correct.
