Question

8кг10гр-3кг80гр+7кг340гр

Answer 1

Пошаговое объяснение:

8кг 10гр - 3кг 80гр + 7кг 340гр =

= 8кг 10гр + 7кг 340гр - 3кг 80гр  =

= (8кг + 7кг - 3кг) + (10 гр + 340гр - 80гр) =

= 12 кг + 270гр = 12кг 270гр

Answer 2

To perform the given arithmetic operation, we'll add the masses:

8 kg 10 g + (-3 kg 80 g) + 7 kg 340 g

Now, let's perform the addition:

First, we need to convert all the masses to the same unit, either all kilograms or all grams. Let's convert them to grams:

8 kg 10 g = 8,000 g + 10 g = 8,010 g -3 kg 80 g = -3,000 g - 80 g = -3,080 g 7 kg 340 g = 7,000 g + 340 g = 7,340 g

Now, add the masses together:

8,010 g - 3,080 g + 7,340 g = 12,270 g

So, the result of the arithmetic operation is 12,270 grams. To convert it back to kg and g:

12,270 g = 12 kg 270 g

Therefore, the final result is 12 kg 270 g.
