D. 5.03 kg

Answer

To express 5 kg 3 g in kilograms using decimals, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Units**: We need to convert grams to kilograms. We know that 1 kg = 1000 grams.

2. **Convert Grams to Kilograms**:
- We have 3 grams. To convert grams to kilograms, we divide by 1000.
- So, \( 3 \text{ g} = \frac{3}{1000} \text{ kg} \).

3. **Add the Kilograms**:
- Now we have 5 kg and we need to add the converted grams in kilograms.
- Therefore, we can express it as:
\[ 5 \text{ kg} + \frac{3}{1000} \text{ kg} \]

4. **Combine the Values**:
- To combine the values, we can convert \( \frac{3}{1000} \) to decimal form.
- \( \frac{3}{1000} = 0.003 \).
- Now we can write:
\[ 5 \text{ kg} + 0.003 \text{ kg} = 5.003 \text{ kg} \]

5. **Final Answer**:
- Therefore, 5 kg 3 g expressed in kilograms using decimals is:
\[ 5.003 \text{ kg} \]
