Answer

To express 2 km 5 m in kilometers using decimals, follow these steps:

### Step-by-Step Solution:

1. **Identify the components**: We have 2 kilometers and 5 meters.
- Here, 2 km is already in kilometers, and we need to convert 5 m into kilometers.

2. **Convert meters to kilometers**:
- We know that 1 kilometer = 1000 meters.
- Therefore, to convert 5 meters to kilometers, we use the conversion factor:
\[ 5 \text{ m} = \frac{5}{1000} \text{ km} \]
- Simplifying this gives:
\[ 5 \text{ m} = 0.005 \text{ km} \]

3. **Add the kilometers**:
- Now we can add the kilometers together:
\[ 2 \text{ km} + 0.005 \text{ km} = 2.005 \text{ km} \]

4. **Final answer**:
- Therefore, 2 km 5 m expressed in kilometers using decimals is:
\[ \text{Answer: } 2.005 \text{ km} \]
