Answer 3

Let's break down the equation step by step:

1. 9 meters - 50 centimeters:

   • 9 meters = 900 centimeters
   • 900 centimeters - 50 centimeters = 850 centimeters

2. 2 tons - 1 ton 6 hundredweight:

   • 1 ton = 20 hundredweight
   • 2 tons = 2 * 20 hundredweight = 40 hundredweight
   • 40 hundredweight - 6 hundredweight = 34 hundredweight

3. 1 hour 20 minutes + 40 minutes:

   • 1 hour = 60 minutes
   • 1 hour 20 minutes = 60 minutes + 20 minutes = 80 minutes
   • 80 minutes + 40 minutes = 120 minutes

4. 1 kilogram - 350 grams:

   • 1 kilogram = 1000 grams
   • 1000 grams - 350 grams = 650 grams

5. 6 decimeters 4 centimeters + 8 centimeters:

   • 6 decimeters = 60 centimeters
   • 60 centimeters + 4 centimeters + 8 centimeters = 72 centimeters

So, the results are:

• 9 meters - 50 centimeters = 850 centimeters
• 2 tons - 1 ton 6 hundredweight = 34 hundredweight
• 1 hour 20 minutes + 40 minutes = 120 minutes
• 1 kilogram - 350 grams = 650 grams
• 6 decimeters 4 centimeters + 8 centimeters = 72 centimeters
