Let’s solve each question step by step.
---
Q1: Insert the Sign > < or =
We need to calculate both sides and compare.
a) 200 + 3000 =
3200
300 + 2000 =
2300
→ 3200 > 2300 →
>
b) 9021 vs 2000 + 900 =
2900
→ 9021 > 2900 →
>
c) 6110 vs 1 + 10 + 6000 =
6011
→ 6110 > 6011 →
>
d) 4002 vs 4200
→ 4002 < 4200 →
<
e) 5,234 vs “10 less than 5,244”
10 less than 5,244 = 5,244 - 10 =
5,234
→ 5,234 = 5,234 →
=

Q2: Which is the biggest number?
a) 2092, 2029, 2209
→ Compare thousands: all are 2xxx
→ Look at hundreds: 2092 (0), 2029 (0), 2209 (2) → 2209 is biggest
b) 9820, 1098, 9018
→ 9820 and 9018 are 9xxx, 1098 is only 1xxx → ignore 1098
→ Between 9820 and 9018: 9820 has 8 in hundreds, 9018 has 0 → 9820 is bigger
---
Q3: Which is the smallest number?
a) 9821, 6719, 682
→ 682 is only 3 digits → smallest
b) 4782, 9822, 8922
→ All 4-digit numbers
→ Smallest thousands digit: 4782 (4) → smallest
---
Q4: Arrange in ascending order (smallest to largest)
a) Numbers: 4067, 467, 4670, 6740
→ 467 is smallest (only 3 digits)
→ Then 4067, then 4670, then 6740
Order:
467 < 4067 < 4670 < 6740
b) Numbers: 9090, 9900, 9009, 9990
→ All start with 9
→ Compare hundreds:
9009 (0), 9090 (0), 9900 (9), 9990 (9)
→ Among 9009 and 9090: tens place — 9009 (0), 9090 (9) → so 9009 < 9090
→ Then 9900 < 9990
Order:
9009 < 9090 < 9900 < 9990
---
Q5: Arrange in descending order (largest to smallest)
a) Numbers: 3093, 3903, 3309, 9309
→ 9309 is biggest (starts with 9)
→ Then among 3xxx: 3903 (hundreds=9), 3309 (hundreds=3), 3093 (hundreds=0)
So: 3903 > 3309 > 3093
Full order:
9309 > 3903 > 3309 > 3093
b) Numbers: 6478, 8674, 7468, 6874
→ Biggest: 8674 (starts with 8)
→ Next: 7468 (starts with 7)
→ Then 6874 and 6478: both start with 6 → compare hundreds: 8 vs 4 → 6874 > 6478
Order:
8674 > 7468 > 6874 > 6478
