Let’s go through each number one by one and write them in expanded form.
Expanded form means breaking the number into hundreds, tens, and ones — like how much each digit is worth based on its place.
For example:
253 = 200 (hundreds) + 50 (tens) + 3 (ones)
We’ll do the same for all 18 numbers.
---
1) 430
→ 4 hundreds = 400
→ 3 tens = 30
→ 0 ones = 0
So:
400 + 30 + 0
2) 59
→ 0 hundreds = 0 (we don’t usually write it if it’s zero)
→ 5 tens = 50
→ 9 ones = 9
So:
50 + 9
3) 646
→ 600 + 40 + 6
So:
600 + 40 + 6
4) 183
→ 100 + 80 + 3
So:
100 + 80 + 3
5) 252
→ 200 + 50 + 2
So:
200 + 50 + 2
6) 497
→ 400 + 90 + 7
So:
400 + 90 + 7
7) 404
→ 400 + 0 + 4 → we skip the zero
So:
400 + 4
8) 986
→ 900 + 80 + 6
So:
900 + 80 + 6
9) 818
→ 800 + 10 + 8
So:
800 + 10 + 8
10) 409
→ 400 + 0 + 9 → skip the zero
So:
400 + 9
11) 512
→ 500 + 10 + 2
So:
500 + 10 + 2
12) 174
→ 100 + 70 + 4
So:
100 + 70 + 4
13) 441
→ 400 + 40 + 1
So:
400 + 40 + 1
14) 124
→ 100 + 20 + 4
So:
100 + 20 + 4
15) 126
→ 100 + 20 + 6
So:
100 + 20 + 6
16) 82
→ 0 hundreds → skip
→ 80 + 2
So:
80 + 2
17) 990
→ 900 + 90 + 0 → skip the zero
So:
900 + 90
18) 496
→ 400 + 90 + 6
So:
400 + 90 + 6

Final Answer:
1) 400 + 30 + 0
2) 50 + 9
3) 600 + 40 + 6
4) 100 + 80 + 3
5) 200 + 50 + 2
6) 400 + 90 + 7
7) 400 + 4
8) 900 + 80 + 6
9) 800 + 10 + 8
10) 400 + 9
11) 500 + 10 + 2
12) 100 + 70 + 4
13) 400 + 40 + 1
14) 100 + 20 + 4
15) 100 + 20 + 6
16) 80 + 2
17) 900 + 90
18) 400 + 90 + 6
