Problem Explanation:
The task involves breaking down each given number into its place values (thousands, hundreds, tens, and ones) and then expressing it as a sum of these place values. This helps in understanding the structure of numbers and their positional values.
Solution:
####
a) 1845
-
Step 1: Identify the place values.
- Thousands: 1
- Hundreds: 8
- Tens: 4
- Ones: 5
-
Step 2: Write the number as a sum of its place values.
- \( 1845 = 1 \text{ thousand} + 8 \text{ hundreds} + 4 \text{ tens} + 5 \text{ ones} \)
- \( 1845 = 1000 + 800 + 40 + 5 \)
-
Final Answer for a):
\[
\boxed{1, 8, 4, 5; 1000, 800, 40, 5}
\]

####
b) 3892
-
Step 1: Identify the place values.
- Thousands: 3
- Hundreds: 8
- Tens: 9
- Ones: 2
-
Step 2: Write the number as a sum of its place values.
- \( 3892 = 3 \text{ thousands} + 8 \text{ hundreds} + 9 \text{ tens} + 2 \text{ ones} \)
- \( 3892 = 3000 + 800 + 90 + 2 \)
-
Final Answer for b):
\[
\boxed{3, 8, 9, 2; 3000, 800, 90, 2}
\]

####
c) 4388
-
Step 1: Identify the place values.
- Thousands: 4
- Hundreds: 3
- Tens: 8
- Ones: 8
-
Step 2: Write the number as a sum of its place values.
- \( 4388 = 4 \text{ thousands} + 3 \text{ hundreds} + 8 \text{ tens} + 8 \text{ ones} \)
- \( 4388 = 4000 + 300 + 80 + 8 \)
-
Final Answer for c):
\[
\boxed{4, 3, 8, 8; 4000, 300, 80, 8}
\]

####
d) 7204
-
Step 1: Identify the place values.
- Thousands: 7
- Hundreds: 2
- Tens: 0
- Ones: 4
-
Step 2: Write the number as a sum of its place values.
- \( 7204 = 7 \text{ thousands} + 2 \text{ hundreds} + 0 \text{ tens} + 4 \text{ ones} \)
- \( 7204 = 7000 + 200 + 0 + 4 \)
-
Final Answer for d):
\[
\boxed{7, 2, 0, 4; 7000, 200, 0, 4}
\]
---
####
e) 9157
-
Step 1: Identify the place values.
- Thousands: 9
- Hundreds: 1
- Tens: 5
- Ones: 7
-
Step 2: Write the number as a sum of its place values.
- \( 9157 = 9 \text{ thousands} + 1 \text{ hundred} + 5 \text{ tens} + 7 \text{ ones} \)
- \( 9157 = 9000 + 100 + 50 + 7 \)
-
Final Answer for e):
\[
\boxed{9, 1, 5, 7; 9000, 100, 50, 7}
\]
---
Final Answers:
\[
\boxed{
\begin{aligned}
&\text{a)} \quad 1, 8, 4, 5; 1000, 800, 40, 5 \\
&\text{b)} \quad 3, 8, 9, 2; 3000, 800, 90, 2 \\
&\text{c)} \quad 4, 3, 8, 8; 4000, 300, 80, 8 \\
&\text{d)} \quad 7, 2, 0, 4; 7000, 200, 0, 4 \\
&\text{e)} \quad 9, 1, 5, 7; 9000, 100, 50, 7 \\
\end{aligned}
}
