To solve the subtraction problems using a number line, we need to follow these steps:
1.
Identify the starting point: This is the larger number in the subtraction problem.
2.
Count back the number of steps: This is the smaller number in the subtraction problem.
3.
Determine the ending point: This is the result of the subtraction.
Let's solve each problem step by step:
---
Problem 1: \( 53 - 41 \)
-
Starting point: 53
-
Count back: 41 steps
-
Ending point:
- From 53, count back 41:
- 53 → 52 → 51 → ... → 13
- The result is 12.
Answer: \( 53 - 41 = 12 \)
---
Problem 2: \( 62 - 27 \)
-
Starting point: 62
-
Count back: 27 steps
-
Ending point:
- From 62, count back 27:
- 62 → 61 → 60 → ... → 35
- The result is 35.
Answer: \( 62 - 27 = 35 \)
---
Problem 3: \( 58 - 17 \)
-
Starting point: 58
-
Count back: 17 steps
-
Ending point:
- From 58, count back 17:
- 58 → 57 → 56 → ... → 41
- The result is 41.
Answer: \( 58 - 17 = 41 \)
---
Problem 4: \( 66 - 55 \)
-
Starting point: 66
-
Count back: 55 steps
-
Ending point:
- From 66, count back 55:
- 66 → 65 → 64 → ... → 11
- The result is 11.
Answer: \( 66 - 55 = 11 \)
---
Problem 5: \( 92 - 27 \)
-
Starting point: 92
-
Count back: 27 steps
-
Ending point:
- From 92, count back 27:
- 92 → 91 → 90 → ... → 65
- The result is 65.
Answer: \( 92 - 27 = 65 \)
---
Final Answers
1. \( 53 - 41 = 12 \)
2. \( 62 - 27 = 35 \)
3. \( 58 - 17 = 41 \)
4. \( 66 - 55 = 11 \)
5. \( 92 - 27 = 65 \)
---
Boxed Final Answer
\[
\boxed{12, 35, 41, 11, 65}
\]
