Все правильно

9т 712 кг =9000кг+712кг=9712кг=9712000г

Answer 2

Yes, you are correct. To convert 9 tons (т) and 712 kilograms (кг) to kilograms, you can use the following calculation:

$9\,т \times 1000\,кг/т + 712\,кг = 9000\,кг + 712\,кг = 9712\,кг$

So, 9 tons and 712 kilograms is indeed equal to 9712 kilograms.
