Answer

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

### Step-by-Step Solution:

1. **Identify the Numbers**: The numbers we need to round off are:
- a. 987
- b. 833
- c. 756
- d. 698
- e. 319
- f. 421

2. **Determine the Nearest Hundreds**:
- **For 987**:
- The nearest hundreds are 900 and 1000.
- The tens digit is 8 (from 987).
- Since 8 is between 5 and 9, we round up to 1000.
- **Rounded Value**: 1000

- **For 833**:
- The nearest hundreds are 800 and 900.
- The tens digit is 3 (from 833).
- Since 3 is between 0 and 4, we round down to 800.
- **Rounded Value**: 800

- **For 756**:
- The nearest hundreds are 700 and 800.
- The tens digit is 5 (from 756).
- Since 5 is between 5 and 9, we round up to 800.
- **Rounded Value**: 800

- **For 698**:
- The nearest hundreds are 600 and 700.
- The tens digit is 9 (from 698).
- Since 9 is between 5 and 9, we round up to 700.
- **Rounded Value**: 700

- **For 319**:
- The nearest hundreds are 300 and 400.
- The tens digit is 1 (from 319).
- Since 1 is between 0 and 4, we round down to 300.
- **Rounded Value**: 300

- **For 421**:
- The nearest hundreds are 400 and 500.
- The tens digit is 2 (from 421).
- Since 2 is between 0 and 4, we round down to 400.
- **Rounded Value**: 400

3. **Final Results**:
- a. 987 → 1000
- b. 833 → 800
- c. 756 → 800
- d. 698 → 700
- e. 319 → 300
- f. 421 → 400

### Summary of Rounded Values:
- a. 1000
- b. 800
- c. 800
- d. 700
- e. 300
- f. 400
