Problem Analysis:
The image contains a series of subtraction problems involving different scenarios. Let's solve each problem step by step.
---
####
Part 1: Slices of Pizza
-
Scenario: A pizza has 7 slices.
-
Questions:
1. If each child eats 1 slice, how many slices will be left?
2. If the children eat 5 slices, how many slices will be left?
3. If the children eat 6 slices, how many slices will be left?
#####
Solution for Part 1:
1.
If each child eats 1 slice:
- Total slices = 7
- Slices eaten = 1
- Slices left = \( 7 - 1 = 6 \)
2.
If the children eat 5 slices:
- Total slices = 7
- Slices eaten = 5
- Slices left = \( 7 - 5 = 2 \)
3.
If the children eat 6 slices:
- Total slices = 7
- Slices eaten = 6
- Slices left = \( 7 - 6 = 1 \)

####
Part 2: Books
-
Scenario: There are 7 books.
-
Questions:
1. If each child takes 1 book, how many books will be left?
2. How many books will be left if the children take 6 books altogether?
3. How many books will be left if the children take 9 books?
#####
Solution for Part 2:
1.
If each child takes 1 book:
- Total books = 7
- Books taken = 1
- Books left = \( 7 - 1 = 6 \)
2.
If the children take 6 books altogether:
- Total books = 7
- Books taken = 6
- Books left = \( 7 - 6 = 1 \)
3.
If the children take 9 books:
- Total books = 7
- Books taken = 9
- Since there are only 7 books available, it is not possible to take 9 books. Therefore, all 7 books will be taken, and 0 books will be left.
- Books left = \( 7 - 7 = 0 \)

####
Part 3: Balls
-
Scenario: The dog buries balls.
-
Questions:
1. If the dog buries 1 ball, how many balls are left?
2. Write a subtraction sentence for this scenario.
3. If the dog buries 5 balls, how many balls are left?
4. Write a subtraction sentence for this scenario.
#####
Solution for Part 3:
1.
If the dog buries 1 ball:
- Total balls = 7
- Balls buried = 1
- Balls left = \( 7 - 1 = 6 \)
- Subtraction sentence: \( 7 - 1 = 6 \)
2.
If the dog buries 5 balls:
- Total balls = 7
- Balls buried = 5
- Balls left = \( 7 - 5 = 2 \)
- Subtraction sentence: \( 7 - 5 = 2 \)
---
Final Answers:
1.
Slices of Pizza:
- If each child eats 1 slice: \( \boxed{6} \)
- If the children eat 5 slices: \( \boxed{2} \)
- If the children eat 6 slices: \( \boxed{1} \)
2.
Books:
- If each child takes 1 book: \( \boxed{6} \)
- If the children take 6 books: \( \boxed{1} \)
- If the children take 9 books: \( \boxed{0} \)
3.
Balls:
- If the dog buries 1 ball: \( \boxed{6} \)
- Subtraction sentence: \( 7 - 1 = 6 \)
- If the dog buries 5 balls: \( \boxed{2} \)
- Subtraction sentence: \( 7 - 5 = 2 \)
---
Boxed Final Answer:
\[
\boxed{6, 2, 1, 6, 1, 0, 6, 7 - 1 = 6, 2, 7 - 5 = 2}
\]
