Express as km using decimals :
(i) 5 m (ii) 888 m (ii) 15 km 88 m.

Answer

To express the given measurements in kilometers using decimals, we will follow these steps:

### Step 1: Understand the Conversion
We know that:
- 1 kilometer (km) = 1000 meters (m)
- Therefore, 1 meter = 1/1000 kilometers = 0.001 kilometers

### Step 2: Convert 5 meters to kilometers
To convert 5 meters to kilometers, we will multiply by 0.001:
\[ 5 \text{ m} \times 0.001 \text{ km/m} = 0.005 \text{ km} \]

### Step 3: Convert 888 meters to kilometers
Next, we convert 888 meters to kilometers using the same method:
\[ 888 \text{ m} \times 0.001 \text{ km/m} = 0.888 \text{ km} \]

### Step 4: Convert 15 kilometers and 88 meters to kilometers
In this case, we already have 15 kilometers. We only need to convert 88 meters to kilometers:
\[ 88 \text{ m} \times 0.001 \text{ km/m} = 0.088 \text{ km} \]
Now, we add this to the 15 kilometers:
\[ 15 \text{ km} + 0.088 \text{ km} = 15.088 \text{ km} \]

### Final Answers
1. 5 m = 0.005 km
2. 888 m = 0.888 km
3. 15 km 88 m = 15.088 km
