Answer 2

I can help you with the calculations you provided. Let's break them down step by step:

Subtraction: 8т264кг - 2т3ц

To subtract these two quantities, we need to convert them to the same unit. Since 1 тонна (т) is equal to 1000 килограммов (кг), we can convert 2 тонны 3 центнера to kilograms by multiplying by 1000 and then subtract from 8 тонн 264 килограмма.

8т264кг - 2т3ц = (8 * 1000 + 264)кг - (2 * 1000 + 3 * 100)кг

= (8000 + 264)кг - (2000 + 300)кг

= 8264кг - 2300кг

= 5964кг

So, the result is 5964 kilograms.

Addition: 8ч27мин + 3ч34мин

To add these two time durations together, we can simply add the hours and minutes separately.

8 hours + 3 hours = 11 hours

27 minutes + 34 minutes = 61 minutes

Since there are 60 minutes in an hour, we can convert the 61 minutes to 1 hour and 1 minute.

11 hours + 1 hour = 12 hours

So, the result is 12 hours and 1 minute.

Addition: 10р.45к. + 23р.94к.

To add these two amounts of money together, we can add the rubles and kopeks separately.

10 rubles + 23 rubles = 33 rubles

45 kopeks + 94 kopeks = 139 kopeks

Since there are 100 kopeks in a ruble, we can convert the 139 kopeks to 1 ruble and 39 kopeks.

33 rubles + 1 ruble = 34 rubles

So, the result is 34 rubles and 39 kopeks.

Subtraction: 17ч5мин - 9ч30мин

To subtract these two time durations, we can subtract the hours and minutes separately.

17 hours - 9 hours = 8 hours

5 minutes - 30 minutes = -25 minutes

Since we have a negative value for minutes, we can convert it to -1 hour and 25 minutes.

8 hours - 1 hour = 7 hours

So, the result is 7 hours and 25 minutes.

Addition: 5ч42мин + 9ч36мин

Similar to the previous addition of time durations, we can add the hours and minutes separately.

5 hours + 9 hours = 14 hours

42 minutes + 36 minutes = 78 minutes

Since there are 60 minutes in an hour, we can convert the 78 minutes to 1 hour and 18 minutes.

14 hours + 1 hour = 15 hours

So, the result is 15 hours and 18 minutes.

Subtraction: 3сут. - 1сут.4ч57мин

To subtract these two time durations, we need to convert them to the same unit. Since 1 сутки (сут.) is equal to 24 hours, we can convert 1 сутки 4 часа 57 минут to hours by multiplying the days by 24 and then subtract from 3 сутки.

3 сутки - 1 сутки 4 часа 57 минут = 3 * 24 - (1 * 24 + 4 + 57/60)

= 72 - (24 + 4 + 57/60)

= 72 - (28 + 57/60)

= 72 - (28 + 0.95)

= 72 - 28.95

= 43.05

So, the result is approximately 43.05 hours.

Division: 1ч21мин48с / 4

To divide this time duration by 4, we need to divide the hours, minutes, and seconds separately.

1 hour / 4 = 0.25 hours

21 minutes / 4 = 5 minutes and 15 seconds

48 seconds / 4 = 12 seconds

So, the result is approximately 0 hours 25 minutes 12 seconds.

Subtraction: 15м22см2 - 9м25дм227см2

To subtract these two areas, we need to convert them to the same unit. Since 1 дециметр (дм) is equal to 10 centimeters (см), we can convert 9 метров 25 дециметров 227 square centimeters to square meters by multiplying the meters by 100 and the decimeters by 10, and then subtract from 15 square meters 22 square centimeters.

15м2 22см2 - 9м25дм227см2 = (15 * 100 + 22)см2 - (9 * 100 + 25 * 10 + 227)см2

= (1500 + 22)см2 - (900 + 250 + 227)см2

= 1522см2 - 1377см2

= 145см2

Since 1 square meter (м2) is equal to 10,000 square centimeters (см2), we can convert the 145 square centimeters to square meters by dividing by 10,000.

145см2 / 10,000 = 0.0145м2

So, the result is approximately 0.0145 square meters.

Subtraction: 12дм3 - 3дм24см3

To subtract these two volumes, we need to convert them to the same unit. Since 1 дециметр (дм) is equal to 10 cubic centimeters (см3), we can convert 3 дециметра 24 cubic centimeters to cubic decimeters by dividing the cubic centimeters by 1000, and then subtract from 12 cubic decimeters.

12дм3 - 3дм24см3 = 12дм3 - (3 * 10 + 24)см3

= 12дм3 - 354см3

Since 1 cubic decimeter (дм3) is equal to 1000 cubic centimeters (см3), we can convert the 354 cubic centimeters to cubic decimeters by dividing by 1000.

354см3 / 1000 = 0.354дм3

So, the result is approximately 12 cubic decimeters - 0.354 cubic decimeters.

= 11.646дм3

So, the result is approximately 11.646 cubic decimeters.

Subtraction: 8т96кг - 429кг

To subtract these two quantities, we need to convert them to the same unit. Since 1 тонна (т) is equal to 1000 килограммов (кг), we can convert 429 kilograms to tons by dividing by 1000, and then subtract from 8 tons 96 kilograms.

8т96кг - 429кг = (8 * 1000 + 96)кг - 429кг

= (8000 + 96)кг - 429кг

= 8096кг - 429кг

= 7667кг

Since there are 1000 kilograms in a ton, we can convert the 7667 kilograms to tons by dividing by 1000.

7667кг / 1000 = 7.667т

So, the result is approximately 7.667 tons.

Addition: 78дм262м2

It seems like there might be a typo in the provided expression. The combination of "дм" (decimeters) and "м2" (square meters) doesn't seem to be valid. Could you please clarify the intended units or provide additional information?

Division: (12кг378г + 4кг575г) / 3 * 9 / 3кг

To evaluate this expression, let's follow the order of operations (parentheses, exponents, multiplication and division from left to right) and apply the correct conversion between kilograms (кг) and grams (г).

First, let's convert the kilograms and grams to grams:

12кг378г = 12 * 1000 + 378 = 12378г

4кг575г = 4 * 1000 + 575 = 4575г

Now, let's perform the addition:

12кг378г + 4кг575г = 12378г + 4575г = 16953г

Now, let's divide by 3:

(12кг378г + 4кг575г) / 3 = 16953г / 3 = 5651г

Now, let's multiply by 9:

(12кг378г + 4кг575г) / 3 * 9 = 5651г * 9 = 50859г

Finally, let's convert back to kilograms:

50859г / 1000 = 50.859кг

Now, let's divide by 3кг:

50.859кг / 3кг = 16.953

So,
