Round off each of the following numbers to the nearest ten, hundred and thousand
a. 5 b. 49 c. 529 d. 3098 e. 84916

Answer

To round off the given numbers to the nearest ten, hundred, and thousand, we will follow these steps:

### Step 1: Round to the Nearest Ten
1. **a. 5**
- The nearest ten is 0 (since 5 is less than 5).
- **Rounded Result: 0**

2. **b. 49**
- The last digit is 9 (greater than 5), so we round up.
- 49 rounds to 50.
- **Rounded Result: 50**

3. **c. 529**
- The last digit is 9 (greater than 5), so we round up.
- 529 rounds to 530.
- **Rounded Result: 530**

4. **d. 3098**
- The last digit is 8 (greater than 5), so we round up.
- 3098 rounds to 3100.
- **Rounded Result: 3100**

5. **e. 84916**
- The last digit is 6 (greater than 5), so we round up.
- 84916 rounds to 84920.
- **Rounded Result: 84920**

### Summary of Rounding to Nearest Ten:
- a. 5 → 0
- b. 49 → 50
- c. 529 → 530
- d. 3098 → 3100
- e. 84916 → 84920

### Step 2: Round to the Nearest Hundred
1. **a. 5**
- The nearest hundred is 0 (since 5 is less than 50).
- **Rounded Result: 0**

2. **b. 49**
- The nearest hundred is 0 (since 49 is less than 50).
- **Rounded Result: 0**

3. **c. 529**
- The last two digits are 29 (less than 50), so we round down.
- 529 rounds to 500.
- **Rounded Result: 500**

4. **d. 3098**
- The last two digits are 98 (greater than 50), so we round up.
- 3098 rounds to 3100.
- **Rounded Result: 3100**

5. **e. 84916**
- The last two digits are 16 (less than 50), so we round down.
- 84916 rounds to 84900.
- **Rounded Result: 84900**

### Summary of Rounding to Nearest Hundred:
- a. 5 → 0
- b. 49 → 0
- c. 529 → 500
- d. 3098 → 3100
- e. 84916 → 84900

### Step 3: Round to the Nearest Thousand
1. **a. 5**
- The nearest thousand is 0 (since 5 is less than 500).
- **Rounded Result: 0**

2. **b. 49**
- The nearest thousand is 0 (since 49 is less than 500).
- **Rounded Result: 0**

3. **c. 529**
- The nearest thousand is 1000 (since 529 is greater than 500).
- **Rounded Result: 1000**

4. **d. 3098**
- The nearest thousand is 3000 (since 98 is less than 500).
- **Rounded Result: 3000**

5. **e. 84916**
- The nearest thousand is 85000 (since 916 is greater than 500).
- **Rounded Result: 85000**

### Summary of Rounding to Nearest Thousand:
- a. 5 → 0
- b. 49 → 0
- c. 529 → 1000
- d. 3098 → 3000
- e. 84916 → 85000

### Final Results:
- Nearest Ten: 0, 50, 530, 3100, 84920
- Nearest Hundred: 0, 0, 500, 3100, 84900
- Nearest Thousand: 0, 0, 1000, 3000, 85000
