Answer 2

Let's solve each of these mathematical expressions step by step:

1. 3 dm 20 mm ÷ 8: First, convert everything to millimeters (mm) for consistency: 3 dm = 3 * 10 cm = 30 cm = 300 mm 20 mm = 20 mm Now, add both values together: 300 mm + 20 mm = 320 mm Now, perform the division: 320 mm ÷ 8 = 40 mm

Answer: 40 mm

2. 5 cnt 40 kg × 3: I'm not sure what "cnt" stands for; please provide the meaning of "cnt." However, I can proceed with the assumption that it means "count." 5 count × 40 kg = 200 kg Now, multiply by 3: 200 kg × 3 = 600 kg

Answer: 600 kg

3. 3h - 1h17 min: To subtract times, we need to convert everything to the same units. Let's convert everything to minutes: 3 hours = 3 * 60 minutes = 180 minutes 1 hour 17 minutes = 1 * 60 minutes + 17 minutes = 77 minutes

Now, perform the subtraction: 180 minutes - 77 minutes = 103 minutes

Answer: 103 minutes

If "cnt" stands for something else, please let me know so I can help you better.
