Which of the following are like decimal numbers ?

Options

A. 1.38, 13.08, 7.8, 2.345
B. 0.8, 8.32, 7.405, 2.003
C. 3.70, 14.1, 3.001, 15.23
D. 7.07, 18.23, 223.45, 0.61

Answer

To determine which of the given options contains like decimal numbers, we need to identify the number of decimal places in each decimal number. Like decimal numbers have the same number of decimal places.

### Step-by-Step Solution:

1. **Identify the Options**: We have four options to analyze:
- Option A: 1.38, 13.08, 7.8, 2.345
- Option B: 0.8, 8.32, 7.405, 2.003
- Option C: 3.70, 14.1, 3.001, 15.23
- Option D: 7.07, 18.23, 223.45, 0.61

2. **Count Decimal Places in Each Option**:
- **Option A**:
- 1.38 → 2 decimal places
- 13.08 → 2 decimal places
- 7.8 → 1 decimal place
- 2.345 → 3 decimal places
- **Conclusion**: Not all numbers have the same decimal places (2, 2, 1, 3). So, these are unlike decimals.

- **Option B**:
- 0.8 → 1 decimal place
- 8.32 → 2 decimal places
- 7.405 → 3 decimal places
- 2.003 → 3 decimal places
- **Conclusion**: Not all numbers have the same decimal places (1, 2, 3, 3). So, these are unlike decimals.

- **Option C**:
- 3.70 → 2 decimal places
- 14.1 → 1 decimal place
- 3.001 → 3 decimal places
- 15.23 → 2 decimal places
- **Conclusion**: Not all numbers have the same decimal places (2, 1, 3, 2). So, these are unlike decimals.

- **Option D**:
- 7.07 → 2 decimal places
- 18.23 → 2 decimal places
- 223.45 → 2 decimal places
- 0.61 → 2 decimal places
- **Conclusion**: All numbers have the same decimal places (2, 2, 2, 2). So, these are like decimals.

3. **Final Answer**: The option that contains like decimal numbers is **Option D**.
