Let's solve the given problems step by step:1. First, we need to convert the units to the same type. Since 1 cm = 10 mm, we can convert 8cM to 80mm. Now, we can subtract 8 from 80mm. So, 2. This problem seems to be incomplete or incorrectly formatted. Please provide more information or clarify the question.3. To solve this problem, we need to convert the units to the same type. Since 1 km = 1000 m, we can convert 300m to 0.3km. Now, we can subtract 0.3km from 8km. So, 4. First, we need to convert the units to the same type. Since 1 km = 1000 m, we can convert 800m to 0.8km. Now, we can add 3km and 0.8km, and then add 300m. So, I hope this helps! Let me know if you have any further questions.
