Question

*Use the fraction number line poster on google classroom to help you decide if you will keep the whole number the same or bounce it up to the next whole number. Then write your estimation problem and solve it.

Example: 3 ⅚ + 2 ⅛
⅚ is close to 1 so 3 wholes + 1 whole = 4
⅛ is close to 0 so the whole number 2 will stay the same.
Estimate 4 + 2 = 6


1 ⅞ + 1 1/5
⅞ is closer to:
⅕ is closer to:
Estimate:

2 ¾ - 1 1/6
¾ is closer to:
⅙ is closer to:
Estimate:

5 2/8 + 1 1/5
2/8 is closer to:
⅕ is closer to:
Estimate:

Answer 1

Let's go through each estimation problem step by step.

### Problem 1: 1 ⅞ + 1 1/5

1. **Analyzing ⅞**:
- ⅞ is very close to 1.
- Therefore, we will round it up and keep the whole number the same at **1 + 1 = 2**.

2. **Analyzing ⅕**:
- ⅕ is relatively small and close to 0.
- Therefore, we keep the whole number the same, which is **1**.

**Estimate:**
- 2 + 1 = **3**

### Problem 2: 2 ¾ - 1 1/6

1. **Analyzing ¾**:
- ¾ is close to **1**.
- We will round it up, so we have **2 + 1 = 3**.

2. **Analyzing ⅙**:
- ⅙ is relatively small and close to 0.
- Therefore, we will keep the whole number the same, which is **1**.

**Estimate:**
- 3 - 1 = **2**

### Problem 3: 5 2/8 + 1 1/5

1. **Analyzing 2/8**:
- 2/8 is equivalent to 1/4 and is closer to **0**.
- Therefore, we keep the whole number the same, which is **5**.

2. **Analyzing ⅕**:
- ⅕ is also relatively small and close to 0.
- Therefore, we keep the whole number the same, which is **1**.

**Estimate:**
- 5 + 1 = **6**

### Summary of Estimations:

1. 1 ⅞ + 1 1/5 → Estimated result: **3**
2. 2 ¾ - 1 1/6 → Estimated result: **2**
3. 5 2/8 + 1 1/5 → Estimated result: **6**
