Question

3т4ц-485кг+9ц98кг= 10км2м-286м+8км54м=

Answer 1

Переведём всё в кг из расчёта 1т = 10 ц = 1000 кг:
3400 кг - 485 кг + 998 кг = 3913 кг = 3 т 9 ц 13 кг

Переведём всё в одну единицу измерения из расчёта 1 км = 1000 м:
10002 - 286 + 8054 = 17770 м = 17 км 770 м

Answer 2

1000кг*400кг-485кг+900кг*98кг=400000-485+88200= 487715кг
1000*2-286+8000*54=2000-286+ 432000= 433714м

Answer 3

To solve this equation, we need to perform addition and subtraction of the given quantities:

1. Start with the first equation:

   3т4ц - 485кг + 9ц98кг

   First, let's add the kilograms and subtract the centigrams:

   3т4ц - 485кг + 9ц98кг = (3т4ц + 9ц98кг) - 485кг

   Now, we add the kilograms and centigrams separately:

   Kilograms: 9кг + (-485кг) = -476кг Centigrams: 34ц + 998ц = 1032ц

   So, the result of the first equation is:

   -476кг + 1032ц

2. Moving on to the second equation:

   10км2м - 286м + 8км54м

   First, let's add the meters and subtract the kilometers:

   10км2м - 286м + 8км54м = (10км2м + 8км54м) - 286м

   Now, we add the meters and kilometers separately:

   Kilometers: 10км + 8км = 18км Meters: 2м + 54м - 286м = -230м

   So, the result of the second equation is:

   18км - 230м

Now you have the results for both equations:

1. -476кг + 1032ц
2. 18км - 230м

Please note that these are not directly comparable, as they have different units (kilograms, centigrams, kilometers, and meters). If you need a specific numerical value or further calculations, please provide more context or clarify your question.
