1. Stating the problem: Convert 45 grams (g) to milligrams (mg) and 6.5 meters (m) to millimeters (mm). 2. Conversion formulas: - 1 gram (g) = 1000 milligrams (mg) - 1 meter (m) = 1000 millimeters (mm) 3. Convert 45 g to mg: $$45\text{ g} = 45 \times 1000 \text{ mg}$$ $$= 45000 \text{ mg}$$ 4. Convert 6.5 m to mm: $$6.5\text{ m} = 6.5 \times 1000 \text{ mm}$$ $$= 6500 \text{ mm}$$ Final answers: - 45 g = 45000 mg - 6.5 m = 6500 mm
