To solve this problem, we need to write each number in expanded form. Expanded form means breaking down the number to show the value of each digit based on its place (ten thousands, thousands, hundreds, tens, and ones).
Let's look at the example provided:
51672 becomes
50000 + 1000 + 600 + 70 + 2.
This breaks it down as:
- 5 is in the ten-thousands place (50,000)
- 1 is in the thousands place (1,000)
- 6 is in the hundreds place (600)
- 7 is in the tens place (70)
- 2 is in the ones place (2)
Now, let's apply this same method to every number in the list:
1.
42347:
- 40,000 + 2,000 + 300 + 40 + 7
2.
12408:
- 10,000 + 2,000 + 400 + 0 + 8 (We usually skip the zero part, so: 10,000 + 2,000 + 400 + 8)
3.
37209:
- 30,000 + 7,000 + 200 + 0 + 9 (Skip zero: 30,000 + 7,000 + 200 + 9)
4.
76803:
- 70,000 + 6,000 + 800 + 0 + 3 (Skip zero: 70,000 + 6,000 + 800 + 3)
5.
90590:
- 90,000 + 0 + 500 + 90 + 0 (Skip zeros: 90,000 + 500 + 90)
6.
21880:
- 20,000 + 1,000 + 800 + 80 + 0 (Skip zero: 20,000 + 1,000 + 800 + 80)
7.
73847:
- 70,000 + 3,000 + 800 + 40 + 7
8.
12100:
- 10,000 + 2,000 + 100 + 0 + 0 (Skip zeros: 10,000 + 2,000 + 100)
9.
56780:
- 50,000 + 6,000 + 700 + 80 + 0 (Skip zero: 50,000 + 6,000 + 700 + 80)
10.
85461:
- 80,000 + 5,000 + 400 + 60 + 1
11.
83200:
- 80,000 + 3,000 + 200 + 0 + 0 (Skip zeros: 80,000 + 3,000 + 200)
12.
57908:
- 50,000 + 7,000 + 900 + 0 + 8 (Skip zero: 50,000 + 7,000 + 900 + 8)
13.
28930:
- 20,000 + 8,000 + 900 + 30 + 0 (Skip zero: 20,000 + 8,000 + 900 + 30)
14.
11096:
- 10,000 + 1,000 + 0 + 90 + 6 (Skip zero: 10,000 + 1,000 + 90 + 6)
Final Answer:
Here are the numbers written in expanded form:
*
42347: 40000 + 2000 + 300 + 40 + 7
*
12408: 10000 + 2000 + 400 + 8
*
37209: 30000 + 7000 + 200 + 9
*
76803: 70000 + 6000 + 800 + 3
*
90590: 90000 + 500 + 90
*
21880: 20000 + 1000 + 800 + 80
*
73847: 70000 + 3000 + 800 + 40 + 7
*
12100: 10000 + 2000 + 100
*
56780: 50000 + 6000 + 700 + 80
*
85461: 80000 + 5000 + 400 + 60 + 1
*
83200: 80000 + 3000 + 200
*
57908: 50000 + 7000 + 900 + 8
*
28930: 20000 + 8000 + 900 + 30
*
11096: 10000 + 1000 + 90 + 6
