Question

420 кг - 2 ц 10 кг =? 7 т 1 кг * 23=? 4 ц 64 гр + 234500 гр =? 2 м 48 см * 4 =? 4 100 т : 5 т =? 12 84 кг : 12 кг=?

Answer 1

Ответ:

420кг-210кг=210кг

7001*23=161023кг

400064+234500=634564

248*4=992

4100т:5т=820т

1284кг:12кг=107

Answer 2

Let's solve each of the arithmetic expressions step-by-step:

1. 420 kg - 2 ц 10 kg: 1 центнер (ц) = 100 kg

Convert 2 ц 10 kg to kg: 2 ц * 100 kg/ц + 10 kg = 210 kg

Now, subtract 210 kg from 420 kg: 420 kg - 210 kg = 210 kg

Answer: 210 kg

2. 7 т 1 кг * 23: 1 тонна (т) = 1000 kg

Convert 7 т 1 кг to kg: 7 т * 1000 kg/т + 1 кг = 7001 kg

Now, multiply 7001 kg by 23: 7001 kg * 23 = 161,023 kg

Answer: 161,023 kg

3. 4 ц 64 г + 234500 г: 1 центнер (ц) = 100 kg

Convert 4 ц to kg: 4 ц * 100 kg/ц = 400 kg

Now, add 400 kg to 234500 grams (since 1 kg = 1000 grams): 400 kg + 234500 g = 400 kg + 234.5 kg = 634.5 kg

Answer: 634.5 kg

4. 2 м 48 см * 4: 1 метр (м) = 100 cm

Convert 2 m to cm: 2 m * 100 cm/m = 200 cm

Now, add 200 cm to 48 cm: 200 cm + 48 cm = 248 cm

Now, multiply 248 cm by 4: 248 cm * 4 = 992 cm

Answer: 992 cm

5. 4100 т : 5 т: 1 тонна (т) = 1000 kg

Convert 4100 т to kg: 4100 т * 1000 kg/т = 4,100,000 kg

Now, divide 4,100,000 kg by 5 т: 4,100,000 kg / 5 т = 820,000 kg

Answer: 820,000 kg

6. 12 84 кг : 12 кг: We need to divide 12,084 kg by 12 kg:

12,084 kg / 12 kg = 1,007

Answer: 1,007

So, the solutions to the arithmetic expressions are as follows:

1. 420 kg - 2 ц 10 kg = 210 kg
2. 7 т 1 кг * 23 = 161,023 kg
3. 4 ц 64 г + 234500 г = 634.5 kg
4. 2 м 48 см * 4 = 992 cm
5. 4,100 т : 5 т = 820,000 kg
6. 12,084 кг : 12 кг = 1,007
