1. We need to find how many millimeters (mm) 8 cm is smaller than 1 meter (m). - First, convert 1 m to cm: $1\text{ m} = 100\text{ cm}$. - Calculate the difference in cm: $100\text{ cm} - 8\text{ cm} = 92\text{ cm}$. - Convert 92 cm to mm: $92\text{ cm} \times 10 = 920\text{ mm}$. So, 8 cm is 920 mm smaller than 1 m. 2. Find how many centimeters (cm) 0.5 m is larger than 0.3 decimeters (dm). - Convert 0.5 m to cm: $0.5\text{ m} = 50\text{ cm}$. - Convert 0.3 dm to cm: $0.3\text{ dm} = 3\text{ cm}$. - Calculate the difference: $50\text{ cm} - 3\text{ cm} = 47\text{ cm}$. So, 0.5 m is 47 cm larger than 0.3 dm. 3. Find the difference between 3 m and 12.5 dm in cm. - Convert 3 m to cm: $3\text{ m} = 300\text{ cm}$. - Convert 12.5 dm to cm: $12.5\text{ dm} = 125\text{ cm}$. - Calculate the difference: $300\text{ cm} - 125\text{ cm} = 175\text{ cm}$. So, the difference between 3 m and 12.5 dm is 175 cm.
