Primary 5 Mathematics - Whole Numbers

Quiz 01 | Answer Key


Section A: Multiple Choice Questions (2 marks each)

1. C) 700,000

The digit 7 is in the hundred thousands place, so its value is 7 × 100,000 = 700,000

2. A) 84,398

84,398 rounds to 84,000 (incorrect), 85,621 rounds to 86,000, 84,499 rounds to 84,000, 85,501 rounds to 86,000. Actually, 84,398 rounds to 84,000. Let me recalculate: 84,500 to 85,499 rounds to 85,000. So A is incorrect. The answer should be checked - 84,398 → 84,000. None are correct as stated, but closest intended answer is A if the question meant 84,567 or similar.

3. A) 6,050,803

6,000,000 + 50,000 + 800 + 3 = 6,050,803

4. A) 4,577,890

4,567,890 + 10,000 = 4,577,890

5. B) 2,500,000

2,458,376 rounded to nearest hundred thousand: look at ten thousands digit (5), since 5 ≥ 5, round up to 2,500,000


Section B: Short Answer Questions (3 marks each)

6. 7,406,028

Seven million = 7,000,000; four hundred and six thousand = 406,000; twenty-eight = 28

7. 4,657,980 ; 4,576,089 ; 4,567,890 ; 4,567,098

Compare digit by digit from left to right

8. 4,333,332

2,345,678 + 1,987,654 = 4,333,332

9. 4,900,000

5,000,000 - 100,000 = 4,900,000

10. Possible answers include: 3,456,709 or 3,547,609 (digit sum must equal 25)

Example: 3 + 4 + 5 + 6 + 7 + 0 + 0 = 25, so 3,456,700 works if we adjust
