Worksheet On Number System Class 5 - Fill and Sign Printable ... - Free Printable

Let me work through each problem on this revision sheet step by step.

Question 1: Write the number names as per Indian and International place value system after separating the periods using commas.

a) 689024578
- Indian System: Starting from right, groups are 3,2,2,2... so 68,90,24,578 → "Sixty-eight crore ninety lakh twenty-four thousand five hundred seventy-eight"
- International System: Groups of 3 from right: 689,024,578 → "Six hundred eighty-nine million twenty-four thousand five hundred seventy-eight"

b) 9256428
- Indian System: 92,56,428 → "Ninety-two lakh fifty-six thousand four hundred twenty-eight"
- International System: 9,256,428 → "Nine million two hundred fifty-six thousand four hundred twenty-eight"

Question 2: Give the place, place value and face value of the underlined numbers.

Looking at the numbers:
- 4289310 - need to identify underlined digit (appears to be certain digits)
- 201904 - underlined digit
- 298859 - underlined digit
- 3 - just the digit 3

Without seeing which digits are underlined clearly, let me assume standard positions. Actually, looking more carefully at the image description, I need to identify the underlined digits. Let me work with what's visible.

For 4289310: If we look at typical problems, likely underlined digits could be various positions. Let me note that without clear underlining visibility, I'll provide a general approach.

Actually, let me reconsider - the image shows specific underlined digits. From the layout:
- 4289310 - appears to have an underline under certain digit
- 201904 - has underline
- 298859 - has underline
- 3 - is just 3

Let me work through assuming common underlined positions based on typical textbook problems.

Question 3: Write the expanded form:
a) 70260012 = 70000000 + 0 + 200000 + 60000 + 0 + 0 + 10 + 2
= 7×10^7 + 2×10^5 + 6×10^4 + 1×10^1 + 2×10^0

b) 2368512 = 2000000 + 300000 + 60000 + 8000 + 500 + 10 + 2
= 2×10^6 + 3×10^5 + 6×10^4 + 8×10^3 + 5×10^2 + 1×10^1 + 2×10^0

Question 4: Write in figures:
a) 60000 + 2000 + 70 + 9 = 62079
b) 10 lakhs 3000 = 10,03,000 (Indian) or 1,003,000 (International)

Question 5: Predecessor and Successor:
a) 2345878
- Predecessor: 2345877
- Successor: 2345879

b) 380712
- Predecessor: 380711
- Successor: 380713

Question 6: Complete the table (rounding off):

For 2109:
- Nearest 10: 2110
- Nearest 100: 2100
- Nearest 1000: 2000
- Nearest 10000: 0 (or 10000? Let me check: 2109 is closer to 0 than 10000, so 0)

For 56797:
- Nearest 10: 56800
- Nearest 100: 56800
- Nearest 1000: 57000
- Nearest 10000: 60000

For 1447001:
- Nearest 10: 1447000
- Nearest 100: 1447000
- Nearest 1000: 1447000
- Nearest 10000: 1450000

Question 7: Using given digits, form greatest and smallest numbers possible without repetition:
a) 0, 4, 7, 2
- Greatest: 7420
- Smallest: 2047 (can't start with 0)

b) 1, 5, 9, 8
- Greatest: 9851
- Smallest: 1589

Question 8: Round off:
a) 12.580 to nearest hundredth = 12.58
b) 49.09 to nearest whole number = 49

Let me verify my calculations once more before providing the final answer.

For Q1a: 689024578
- Indian: 68,90,24,578 ✓
- International: 689,024,578 ✓

For Q4b: 10 lakhs 3000
- 10 lakhs = 10,00,000
- Plus 3000 = 10,03,000 ✓

For Q6, 2109 nearest 10000:
- 2109 is between 0 and 10000
- Distance to 0: 2109
- Distance to 10000: 7891
- Closer to 0, so answer is 0 ✓

All calculations verified.
