28кг400г+45кг700г=? 62кг250г-7кг500г=? 5ц32кг*18=? 20ц80кг*25=? 37т8ц/14=? 70т/50=?

Answer 1

28кг400г+45кг700г=74 кг 100 г

 62кг250г-7кг500г=54 кг 750 г

5ц32кг*18=95 ц 76 кг

20ц80кг*25=520 ц

 37т8ц/14=2 т 7 ц

 70т/50=1 т 4 ц

Answer 2

To solve the given arithmetic operations, let's break down each operation step by step.

Addition

The first operation is an addition: 28 kg 400 g + 45 kg 700 g

To add these two weights, we can simply add the kilograms and the grams separately: 28 kg + 45 kg = 73 kg 400 g + 700 g = 1100 g

However, 1100 g is more than 1 kg, so we can convert the excess grams into kilograms: 1100 g = 1 kg 100 g

So, the total sum is: 73 kg + 1 kg = 74 kg 100 g

Subtraction

The second operation is a subtraction: 62 kg 250 g - 7 kg 500 g

Similarly, we can subtract the kilograms and the grams separately: 62 kg - 7 kg = 55 kg 250 g - 500 g = -250 g

Since the result is negative, we need to borrow 1 kg from the kilograms: 55 kg - 1 kg = 54 kg 250 g + 1000 g - 500 g = 750 g

So, the total difference is: 54 kg 750 g

Multiplication

The third operation is a multiplication: 5 ц 32 кг * 18

To multiply these values, we can first convert centners to kilograms: 5 ц * 100 кг/ц = 500 кг Then we can perform the multiplication: 500 кг + 32 кг = 532 кг 532 кг * 18 = 9576 кг

So, the total product is: 9576 кг

Multiplication (Large Numbers)

The fourth operation is a multiplication involving larger numbers: 20 ц 80 кг * 25

First, convert the centners to kilograms: 20 ц * 100 кг/ц = 2000 кг Then perform the multiplication: 2000 кг + 80 кг = 2080 кг 2080 кг * 25 = 52000 кг

So, the total product is: 52000 кг

Division

The fifth operation involves division: 37 т 8 ц / 14

First, convert the tons to kilograms and add the centners: 37 т * 1000 кг/т = 37000 кг 37000 кг + 8 ц * 100 кг/ц = 37800 кг Then perform the division: 37800 кг / 14 = 2700 кг

So, the result of the division is: 2700 кг

Division (Large Numbers)

The final operation is another division: 70 т / 50

First, convert the tons to kilograms: 70 т * 1000 кг/т = 70000 кг Then perform the division: 70000 кг / 50 = 1400 кг

So, the result of the division is: 1400 кг

In summary, the results of the given arithmetic operations are: - 28 kg 400 g + 45 kg 700 g = 74 kg 100 g - 62 kg 250 g - 7 kg 500 g = 54 kg 750 g - 5 ц 32 кг * 18 = 9576 кг - 20 ц 80 кг * 25 = 52000 кг - 37 т 8 ц / 14 = 2700 кг - 70 т / 50 = 1400 кг
