I'll solve each question step by step.

Q1: Comparing 3-digit numbers using >, <, or =

Let me work through each comparison:

Column 1:
- 480 vs 408: Compare hundreds (4=4), then tens (8>0). So 480 > 408
- 776 vs 767: Compare hundreds (7=7), then tens (7>6). So 776 > 767
- 812 vs 643: Compare hundreds (8>6). So 812 > 643
- 990 vs 917: Compare hundreds (9=9), then tens (9>1). So 990 > 917

Column 2:
- 835 vs 740: Compare hundreds (8>7). So 835 > 740
- 603 vs 603: All digits are the same. So 603 = 603
- 341 vs 314: Compare hundreds (3=3), then tens (4>1). So 341 > 314
- 561 vs 567: Compare hundreds (5=5), then tens (6=6), then ones (1<7). So 561 < 567

Column 3:
- 521 vs 347: Compare hundreds (5>3). So 521 > 347
- 500 vs 700: Compare hundreds (5<7). So 500 < 700
- 852 vs 751: Compare hundreds (8>7). So 852 > 751
- 105 vs 105: All digits are the same. So 105 = 105

Q2: Writing in ascending order (smallest to largest)

Row 1: 231, 469, 860, 629
- Smallest is 231, then 469, then 629, then 860
- Answer: 231, 469, 629, 860

Row 2: 135, 318, 440, 587
- Already in order! Let me verify: 135 < 318 < 440 < 587 ✓
- Answer: 135, 318, 440, 587

Row 3: 412, 127, 421, 128
- Smallest is 127, then 128, then 412, then 421
- Answer: 127, 128, 412, 421

Row 4: 798, 666, 615, 738
- Smallest is 615, then 666, then 738, then 798
- Answer: 615, 666, 738, 798

Row 5: 396, 666, 951, 723
- Smallest is 396, then 666, then 723, then 951
- Answer: 396, 666, 723, 951

Q3: Writing in descending order (largest to smallest)

Row 1: 231, 469, 860, 629
- Largest is 860, then 629, then 469, then 231
- Answer: 860, 629, 469, 231

Row 2: 135, 318, 440, 587
- Largest is 587, then 440, then 318, then 135
- Answer: 587, 440, 318, 135

Row 3: 412, 127, 421, 128
- Largest is 421, then 412, then 128, then 127
- Answer: 421, 412, 128, 127

Row 4: 798, 666, 615, 738
- Largest is 798, then 738, then 666, then 615
- Answer: 798, 738, 666, 615

Row 5: 396, 666, 951, 723
- Largest is 951, then 723, then 666, then 396
- Answer: 951, 723, 666, 396

Final Answer:

Q1:
Column 1: 480 > 408, 776 > 767, 812 > 643, 990 > 917
Column 2: 835 > 740, 603 = 603, 341 > 314, 561 < 567
Column 3: 521 > 347, 500 < 700, 852 > 751, 105 = 105
