The task involves completing number bonds where the "whole" is given, and you need to find the missing "part." A number bond shows how a whole number can be split into two parts. The relationship between the whole and its parts can be expressed as:
\[
\text{Whole} = \text{Part 1} + \text{Part 2}
\]
To find the missing part, you can use the formula:
\[
\text{Missing Part} = \text{Whole} - \text{Known Part}
\]
Let's solve each number bond step by step.
Row 1:
1.
Whole: 12, Part: 7
\[
\text{Missing Part} = 12 - 7 = 5
\]
So, the missing part is
5.
2.
Whole: 9, Part: 6
\[
\text{Missing Part} = 9 - 6 = 3
\]
So, the missing part is
3.
3.
Whole: 16, Part: 8
\[
\text{Missing Part} = 16 - 8 = 8
\]
So, the missing part is
8.
Row 2:
4.
Whole: 10, Part: 3
\[
\text{Missing Part} = 10 - 3 = 7
\]
So, the missing part is
7.
5.
Whole: 11, Part: 9
\[
\text{Missing Part} = 11 - 9 = 2
\]
So, the missing part is
2.
6.
Whole: 7, Part: 1
\[
\text{Missing Part} = 7 - 1 = 6
\]
So, the missing part is
6.
Row 3:
7.
Whole: 14, Part: 4
\[
\text{Missing Part} = 14 - 4 = 10
\]
So, the missing part is
10.
8.
Whole: 15, Part: 7
\[
\text{Missing Part} = 15 - 7 = 8
\]
So, the missing part is
8.
9.
Whole: 6, Part: 3
\[
\text{Missing Part} = 6 - 3 = 3
\]
So, the missing part is
3.
Row 4:
10.
Whole: 17, Part: 8
\[
\text{Missing Part} = 17 - 8 = 9
\]
So, the missing part is
9.
11.
Whole: 13, Part: 5
\[
\text{Missing Part} = 13 - 5 = 8
\]
So, the missing part is
8.
12.
Whole: 4, Part: 2
\[
\text{Missing Part} = 4 - 2 = 2
\]
So, the missing part is
2.
Final Answer:
\[
\boxed{
\begin{array}{ccc}
5 & 3 & 8 \\
7 & 2 & 6 \\
10 & 8 & 3 \\
9 & 8 & 2 \\
\end{array}
}
\]
