Ответ:сделай лучшим ответом

2км 425м*8=19кг 400м

26м 85см*7=190м 80см

18ц 02кг*4=32ц 8кг

1т 250кг*8=10т

230см 2мм*4=920см 8мм

190см 2мм*5=951см

Answer 2

To perform the arithmetic calculations, let's solve each operation step by step:

1. Subtraction of lengths: 2 km 425 m - 826 m 85 cm

   First, convert 2 km to meters: 2 km = 2000 m

   Now, we can subtract the lengths: 2000 m + 425 m - 826 m = 1599 m

   Since we have 85 cm, we need to convert it to meters by dividing by 100: 1599 m - (826 m + 85 cm ÷ 100) = 1599 m - (826 m + 0.85 m) = 772.15 m

   Therefore, 2 km 425 m - 826 m 85 cm is equal to 772.15 meters.

2. Multiplication of quantities: 718 ц 02 кг * 41 т 250 кг

   First, convert the units to the same type (grams) to perform multiplication: 718 ц 02 кг = 71802 kg (1 ц = 100 kg) 41 т 250 кг = 41250 kg (1 т = 1000 kg)

   Now, we can multiply the quantities: 71802 kg * 41250 kg = 2966801250 kg^2

   Therefore, 718 ц 02 кг * 41 т 250 кг is equal to 2966801250 kilograms squared.

3. Subtraction of areas: 8230 см^2 - 4190 мм^2

   First, convert the units to the same type (square centimeters) to perform subtraction: 8230 см^2 = 8230 cm^2 4190 мм^2 = 4190 mm^2 = 41.9 cm^2 (1 mm = 0.1 cm)

   Now, we can subtract the areas: 8230 cm^2 - 41.9 cm^2 = 8188.1 cm^2

   Therefore, 8230 см^2 - 4190 мм^2 is equal to 8188.1 square centimeters.
