Express in km using decimals:
(i) 65m
(ii) 284m
(iii) 3 km 5m

Answer

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

### Step 1: Convert 65 meters to kilometers
1. **Understand the conversion factor:**
- 1 meter = 1/1000 kilometers.
2. **Calculate the conversion:**
- 65 meters = 65 × (1/1000) kilometers = 65/1000 kilometers.
3. **Express in decimal form:**
- 65/1000 = 0.065 kilometers.

### Step 2: Convert 284 meters to kilometers
1. **Use the same conversion factor:**
- 1 meter = 1/1000 kilometers.
2. **Calculate the conversion:**
- 284 meters = 284 × (1/1000) kilometers = 284/1000 kilometers.
3. **Express in decimal form:**
- 284/1000 = 0.284 kilometers.

### Step 3: Convert 3 kilometers and 5 meters to kilometers
1. **Separate the kilometers and meters:**
- We have 3 kilometers and 5 meters.
2. **Convert 5 meters to kilometers:**
- 5 meters = 5 × (1/1000) kilometers = 5/1000 kilometers = 0.005 kilometers.
3. **Add the kilometers:**
- Total = 3 kilometers + 0.005 kilometers = 3.005 kilometers.

### Final Answers:
(i) 65 meters = 0.065 kilometers
(ii) 284 meters = 0.284 kilometers
(iii) 3 kilometers 5 meters = 3.005 kilometers
