D. `73.80` kg

Answer

To convert grams to kilograms using decimals, follow these steps:

### Step-by-Step Solution:

1. **Understand the Conversion Factor**:
We know that 1 kilogram (kg) is equal to 1000 grams (g). Therefore, to convert grams to kilograms, we need to divide the number of grams by 1000.

2. **Set Up the Division**:
We have 7380 grams. To convert this to kilograms, we will divide 7380 by 1000.
\[ \text{Kilograms} = \frac{7380 \text{ g}}{1000} \]

3. **Perform the Division**:
When we divide 7380 by 1000, we can think of it as moving the decimal point three places to the left (since 1000 has three zeros).
\[ 7380 \div 1000 = 7.380 \]

4. **Write the Result**:
Thus, 7380 grams is equal to 7.380 kilograms.
\[ \text{Final Answer: } 7380 \text{ g} = 7.380 \text{ kg} \]
