I'll work through this inverse relationships worksheet step by step.
The worksheet shows addition and subtraction facts that are related to each other. For each pair, if we know one fact, we can find the missing number in the related fact.
Let me solve each problem:
Left column:
1. 7 + 7 = 14, so 14 - 7 =
7 ✓ (given)
2. 9 + 3 = 12, so 12 - 9 =
3
3. 7 + 7 = 14, so 14 - 7 =
7 ✓ (given)
4. 9 + 1 = 10, so 10 - 9 =
1
5. 2 + 7 = 9, so 9 - 2 =
7
6. 8 + 2 = 10, so 10 - 8 =
2
7. 4 + 9 = 13, so 13 - 4 =
9
8. 5 + 6 = 11, so 11 - 5 =
6
Right column:
1. 3 + 4 = 7, so 7 - 4 =
3 ✓ (given)
2. 1 + 1 = 2, so 2 - 1 =
1
3. 5 + 7 = 12, so 12 - 5 =
7
4. 3 + 6 = 9, so 9 - 3 =
6
5. 6 + 9 = 15, so 15 - 6 =
9
6. 8 + 1 = 9, so 9 - 8 =
1
7. 1 + 4 = 5, so 5 - 1 =
4
8. 1 + 5 = 6, so 6 - 1 =
5
Let me verify my answers:
- 12 - 9 = 3 ✓
- 10 - 9 = 1 ✓
- 9 - 2 = 7 ✓
- 10 - 8 = 2 ✓
- 13 - 4 = 9 ✓
- 11 - 5 = 6 ✓
- 2 - 1 = 1 ✓
- 12 - 5 = 7 ✓
- 9 - 3 = 6 ✓
- 15 - 6 = 9 ✓
- 9 - 8 = 1 ✓
- 5 - 1 = 4 ✓
- 6 - 1 = 5 ✓
Final Answer:
Left column blanks: 3, 1, 7, 2, 9, 6
Right column blanks: 1, 7, 6, 9, 1, 4, 5
