To solve this problem, we need to understand what a "number bond" is. A number bond shows how numbers can be split into parts. In this case, the top number is the total, and the two bottom numbers are the parts that add up to the total.
Let's go through each number bond one by one:
1.
First Row:
- 19 = 10 + ?
- 19 - 10 = 9
- 18 = 9 + ?
- 18 - 9 = 9
- 16 = ? + 6
- 16 - 6 = 10
2.
Second Row:
- 16 = 9 + ?
- 16 - 9 = 7
- 15 = ? + 7
- 15 - 7 = 8
- 14 = ? + 8
- 14 - 8 = 6
3.
Third Row:
- 14 = 9 + ?
- 14 - 9 = 5
- 13 = 7 + ?
- 13 - 7 = 6
- 13 = ? + 5
- 13 - 5 = 8
4.
Fourth Row:
- 12 = 6 + ?
- 12 - 6 = 6
- 12 = ? + 5
- 12 - 5 = 7
- 11 = 4 + ?
- 11 - 4 = 7
Final Answer:
9, 9, 10, 7, 8, 6, 5, 6, 8, 6, 7, 7
