Answer 3

Let's break down the calculations step by step:

1. Convert 20 km 120 m to meters: 20 km = 20,000 meters 20,000 meters + 120 meters = 20,120 meters

2. Calculate 3 square meters in proportion to 8 square meters: 3 m^2 : 8 m^2 = 3/8 This cannot be simplified further, so the result is 3/8 square meters.

3. Convert 16 hours 45 minutes to minutes: 16 hours * 60 minutes/hour = 960 minutes 960 minutes + 45 minutes = 1005 minutes

4. Subtract 135 minutes from 1005 minutes: 1005 minutes - 135 minutes = 870 minutes

5. Convert 870 minutes to hours and minutes: 870 minutes ÷ 60 minutes/hour = 14 hours 30 minutes

6. Convert 20 kg to grams and add to 202,000 grams: 20 kg = 20,000 grams 20,000 grams + 202,000 grams = 222,000 grams

So the final results are:

• 20 km 120 m = 20,120 meters
• 3 m^2 : 8 m^2 = 3/8 square meters
• 16 hours 45 minutes = 1005 minutes or 16 hours 45 minutes
• 16 hours 45 minutes - 135 minutes = 14 hours 30 minutes
• 20 kg + 202,000 grams = 222,000 grams
