Problem Explanation:
The task involves writing numbers in
expanded form. Expanded form breaks down a number into the value of each digit based on its place value (hundreds, tens, and ones). For example, the number
234 is written as
200 + 30 + 4 because:
- The digit
2 is in the hundreds place, so it represents
200.
- The digit
3 is in the tens place, so it represents
30.
- The digit
4 is in the ones place, so it represents
4.
Solution:
We will break down each number into its expanded form by identifying the hundreds, tens, and ones places.
#### Given Example:
-
234:
- Hundreds: 2 (200)
- Tens: 3 (30)
- Ones: 4 (4)
- Expanded form:
200 + 30 + 4
#### Remaining Numbers:
1.
513:
- Hundreds: 5 (500)
- Tens: 1 (10)
- Ones: 3 (3)
- Expanded form:
500 + 10 + 3
2.
673:
- Hundreds: 6 (600)
- Tens: 7 (70)
- Ones: 3 (3)
- Expanded form:
600 + 70 + 3
3.
947:
- Hundreds: 9 (900)
- Tens: 4 (40)
- Ones: 7 (7)
- Expanded form:
900 + 40 + 7
4.
682:
- Hundreds: 6 (600)
- Tens: 8 (80)
- Ones: 2 (2)
- Expanded form:
600 + 80 + 2
5.
870:
- Hundreds: 8 (800)
- Tens: 7 (70)
- Ones: 0 (0)
- Expanded form:
800 + 70 + 0
6.
701:
- Hundreds: 7 (700)
- Tens: 0 (0)
- Ones: 1 (1)
- Expanded form:
700 + 0 + 1
7.
457:
- Hundreds: 4 (400)
- Tens: 5 (50)
- Ones: 7 (7)
- Expanded form:
400 + 50 + 7
8.
198:
- Hundreds: 1 (100)
- Tens: 9 (90)
- Ones: 8 (8)
- Expanded form:
100 + 90 + 8
9.
355:
- Hundreds: 3 (300)
- Tens: 5 (50)
- Ones: 5 (5)
- Expanded form:
300 + 50 + 5
Final Answer:
\[
\begin{array}{c|c|c|c}
\text{Number} & \text{Hundreds} & \text{Tens} & \text{Ones} \\
\hline
513 & 500 & 10 & 3 \\
673 & 600 & 70 & 3 \\
947 & 900 & 40 & 7 \\
682 & 600 & 80 & 2 \\
870 & 800 & 70 & 0 \\
701 & 700 & 0 & 1 \\
457 & 400 & 50 & 7 \\
198 & 100 & 90 & 8 \\
355 & 300 & 50 & 5 \\
\end{array}
\]
\boxed{
\begin{aligned}
513 &: 500 + 10 + 3 \\
673 &: 600 + 70 + 3 \\
947 &: 900 + 40 + 7 \\
682 &: 600 + 80 + 2 \\
870 &: 800 + 70 + 0 \\
701 &: 700 + 0 + 1 \\
457 &: 400 + 50 + 7 \\
198 &: 100 + 90 + 8 \\
355 &: 300 + 50 + 5 \\
\end{aligned}
}
