17. 6.4 cm = ____ mm
18. 37 mm = ____ cm
19. 2.3 km = ____ m
20. 8,500 m = ____ km
1. **Problem:** Convert $2.5$ kilograms to grams.
2. **Formula:** $1\text{ kg} = 1000\text{ g}$.
3. **Calculation:**
$$2.5\text{ kg} = 2.5 \times 1000\text{ g} = 2500\text{ g}$$
4. **Answer:** $2.5\text{ kg} = 2500\text{ g}$.
1. **Problem:** Convert $3500$ grams to kilograms.
2. **Formula:** $1\text{ kg} = 1000\text{ g}$, so to convert grams to kilograms, divide by $1000$.
3. **Calculation:**
$$3500\text{ g} = \frac{3500}{1000}\text{ kg} = \cancel{\frac{3500}{1000}}^{3.5}\text{ kg}$$
4. **Answer:** $3500\text{ g} = 3.5\text{ kg}$.
1. **Problem:** Convert $1.75$ meters to centimeters.
2. **Formula:** $1\text{ m} = 100\text{ cm}$.
3. **Calculation:**
$$1.75\text{ m} = 1.75 \times 100\text{ cm} = 175\text{ cm}$$
4. **Answer:** $1.75\text{ m} = 175\text{ cm}$.
1. **Problem:** Convert $425$ centimeters to meters.
2. **Formula:** $1\text{ m} = 100\text{ cm}$, so divide by $100$ to convert cm to m.
3. **Calculation:**
$$425\text{ cm} = \frac{425}{100}\text{ m} = \cancel{\frac{425}{100}}^{4.25}\text{ m}$$
4. **Answer:** $425\text{ cm} = 4.25\text{ m}$.
1. **Problem:** Convert $4.8$ liters to milliliters.
2. **Formula:** $1\text{ L} = 1000\text{ mL}$.
3. **Calculation:**
$$4.8\text{ L} = 4.8 \times 1000\text{ mL} = 4800\text{ mL}$$
4. **Answer:** $4.8\text{ L} = 4800\text{ mL}$.
1. **Problem:** Convert $2250$ milliliters to liters.
2. **Formula:** $1\text{ L} = 1000\text{ mL}$, so divide by $1000$ to convert mL to L.
3. **Calculation:**
$$2250\text{ mL} = \frac{2250}{1000}\text{ L} = \cancel{\frac{2250}{1000}}^{2.25}\text{ L}$$
4. **Answer:** $2250\text{ mL} = 2.25\text{ L}$.
1. **Problem:** Convert $6.4$ centimeters to millimeters.
2. **Formula:** $1\text{ cm} = 10\text{ mm}$.
3. **Calculation:**
$$6.4\text{ cm} = 6.4 \times 10\text{ mm} = 64\text{ mm}$$
4. **Answer:** $6.4\text{ cm} = 64\text{ mm}$.
1. **Problem:** Convert $37$ millimeters to centimeters.
2. **Formula:** $1\text{ cm} = 10\text{ mm}$, so divide by $10$ to convert mm to cm.
3. **Calculation:**
$$37\text{ mm} = \frac{37}{10}\text{ cm} = \cancel{\frac{37}{10}}^{3.7}\text{ cm}$$
4. **Answer:** $37\text{ mm} = 3.7\text{ cm}$.
1. **Problem:** Convert $2.3$ kilometers to meters.
2. **Formula:** $1\text{ km} = 1000\text{ m}$.
3. **Calculation:**
$$2.3\text{ km} = 2.3 \times 1000\text{ m} = 2300\text{ m}$$
4. **Answer:** $2.3\text{ km} = 2300\text{ m}$.
1. **Problem:** Convert $8500$ meters to kilometers.
2. **Formula:** $1\text{ km} = 1000\text{ m}$, so divide by $1000$ to convert m to km.
3. **Calculation:**
$$8500\text{ m} = \frac{8500}{1000}\text{ km} = \cancel{\frac{8500}{1000}}^{8.5}\text{ km}$$
4. **Answer:** $8500\text{ m} = 8.5\text{ km}$.
