Question

6ч20мин-34мин , 10м6см +8дм7см, 8т6кг-15ц 28кг.

Answer 1

1) 6ч20м - 34м = 5ч46м

2) 10м6см + 8дм7см = 106см + 87см = 1м93см

3) 8т6кг - 15ц28кг = 8006кг - 1528кг = 6т4ц78кг

Answer 2

6ч20м-34м=5ч46м
10м6см+8дм7см=106см+87см=193см (или 1м93см)
8т6кг-15ц28кг=8006кг-1528кг=6478кг (или 6т4ц78кг)

Answer 3

To solve the given arithmetic expressions, let's perform the calculations step by step:

1. 6 hours 20 minutes - 34 minutes: Convert all the units to minutes to make the calculation easier. 6 hours = 6 * 60 = 360 minutes 20 minutes - 34 minutes = -14 minutes

Result: 6 hours 20 minutes - 34 minutes = 5 hours 46 minutes

2. 10 meters 6 centimeters + 8 decimeters 7 centimeters: Convert the measurements to centimeters to add them. 10 meters = 10 * 100 = 1000 centimeters 8 decimeters = 8 * 10 = 80 centimeters

Now add the centimeters together: 1000 centimeters + 80 centimeters + 7 centimeters = 1087 centimeters

Result: 10 meters 6 centimeters + 8 decimeters 7 centimeters = 10 meters 87 centimeters (We can convert the centimeters back to meters and centimeters: 10 meters 87 centimeters = 11 meters 87 centimeters)

3. 8 tons 6 kilograms - 15 centigrams 28 kilograms: First, let's convert tons to kilograms since the second measurement is in kilograms. 8 tons = 8 * 1000 = 8000 kilograms

Now, subtract the kilograms: 8000 kilograms - 15 kilograms = 7985 kilograms

Result: 8 tons 6 kilograms - 15 centigrams 28 kilograms = 7985 kilograms.

So, the final results are:

1. 6 hours 20 minutes - 34 minutes = 5 hours 46 minutes
2. 10 meters 6 centimeters + 8 decimeters 7 centimeters = 11 meters 87 centimeters
3. 8 tons 6 kilograms - 15 centigrams 28 kilograms = 7985 kilograms.
