Question

Для выплавки 6 одинаковых котлов израсходовали 36 ц 30 кг чугуна.Какова масса 3 таких котлов?

Answer 1

1) 3630:6=605кг-масса 1 котла
2)605*3=1815кг
Ответ:масса 3 котлов 1815 кг
1815 кг=18ц 15кг

Answer 2

1)36,30 : 6=6,5 (ц)-на 1 котёл
2) 6,5*3=18,15 (ц)-3 котла
Ответ: масса 3 котлов равна 18 ц 15 кг (18,15 ц).

Answer 3

Calculation of the Mass of 3 Identical Boilers

To find the mass of 3 identical boilers, given that 6 identical boilers required 36 cwt 30 kg of pig iron for smelting, we can use the following steps:

1. Calculate the Mass of 1 Boiler: - First, we need to find the mass of 1 boiler by dividing the total mass of pig iron used by the number of boilers. - The mass of 1 boiler can be calculated using the formula: ``` Mass of 1 boiler = Total mass of pig iron / Number of boilers ```

2. Calculate the Mass of 3 Boilers: - Once we have the mass of 1 boiler, we can then calculate the mass of 3 boilers by multiplying the mass of 1 boiler by 3.

Let's proceed with the calculations.

Calculation

1. Calculate the Mass of 1 Boiler: - Total mass of pig iron = 36 cwt 30 kg - Number of boilers = 6 - Using the given values, we can calculate the mass of 1 boiler: ``` Mass of 1 boiler = 36 cwt 30 kg / 6 ```

- After calculating the mass of 1 boiler, we can then proceed to find the mass of 3 boilers by multiplying the mass of 1 boiler by 3.

2. Calculate the Mass of 3 Boilers: - Mass of 1 boiler = Result from the previous calculation - Number of boilers = 3 - Using the calculated mass of 1 boiler, we can find the mass of 3 boilers: ``` Mass of 3 boilers = Mass of 1 boiler * 3 ```

Result

The mass of 3 identical boilers can be calculated using the above steps.

I will now calculate the mass of 1 boiler and then the mass of 3 boilers using the provided information.

Calculation

1. Calculate the Mass of 1 Boiler: - Total mass of pig iron = 36 cwt 30 kg - Number of boilers = 6 - Mass of 1 boiler = 36 cwt 30 kg / 6 - Mass of 1 boiler = 6 cwt 5 kg

2. Calculate the Mass of 3 Boilers: - Mass of 1 boiler = 6 cwt 5 kg - Number of boilers = 3 - Mass of 3 boilers = 6 cwt 5 kg * 3 - Mass of 3 boilers = 18 cwt 15 kg

Answer

The mass of 3 identical boilers is 18 cwt 15 kg.
