A farmer had a coil of wire 243m long. He needed to cut it into pieces 450cm long. How many complete lengths could he make?

To determine the number of complete 450 cm lengths that can be cut from a 243-meter coil of wire, let’s convert everything to the same unit, then divide.

### Step-by-Step Solution

1. **Convert 243 meters to centimeters:**

   Since \( 1 \text{ meter} = 100 \text{ centimeters} \),
   \[
   243 \text{ m} = 243 \times 100 = 24300 \text{ cm}
   \]

2. **Divide the total length by the length of each piece:**

   Each piece needs to be \( 450 \text{ cm} \) long, so:
   \[
   \frac{24300}{450} = 54
   \]

3. **Conclusion:**
   The farmer can make **54 complete lengths** of 450 cm each from the 243-meter coil.

Here are 5 related questions for further practice:

1. If the farmer had a coil of 500 m, how many 450 cm pieces could he make?
2. What would be the leftover length if the farmer only needs 50 pieces?
3. If the farmer decides to cut 300 cm pieces instead, how many can he make?
4. How many 150 cm lengths could be cut from a 200 m coil?
5. If another coil is 600 cm shorter, how many 450 cm pieces could he make from it?

**Tip:** Always convert all measurements to the same unit before performing division to avoid errors.
