1) 37дм 8 см
2) 37 дм 8 см 
3) 18 т 8 ц
4) 18 т 8 ц

Answer 2

Calculation 1: 12дм6см * 3

To perform this calculation, we need to multiply 12дм6см by 3.

First, let's convert 12дм6см to a single unit. Since 1дм is equal to 10см, we can convert 12дм to см by multiplying it by 10. This gives us 120см. Adding 6см to this, we get a total of 126см.

Now, we can multiply 126см by 3. The result is 378см.

To express this result in the form of дм and см, we need to divide 378см by 10 to get the number of дм and find the remainder as the number of см. Dividing 378 by 10 gives us 37 with a remainder of 8. Therefore, the final result is 37дм8см.

Calculation 2: 126см * 3

To perform this calculation, we need to multiply 126см by 3.

Multiplying 126см by 3 gives us 378см.

To express this result in the form of дм and см, we need to divide 378см by 10 to get the number of дм and find the remainder as the number of см. Dividing 378 by 10 gives us 37 with a remainder of 8. Therefore, the final result is 37дм8см.

Calculation 3: 4т7ц * 4

To perform this calculation, we need to multiply 4т7ц by 4.

First, let's convert 4т to ц by multiplying it by 100. This gives us 400ц. Adding 7ц to this, we get a total of 407ц.

Now, we can multiply 407ц by 4. The result is 1628ц.

To express this result in the form of т and ц, we need to divide 1628ц by 100 to get the number of т and find the remainder as the number of ц. Dividing 1628 by 100 gives us 16 with a remainder of 28. Therefore, the final result is 16т28ц.

Calculation 4: 4т7ц * 4

To perform this calculation, we need to multiply 4т7ц by 4.

Multiplying 4т7ц by 4 gives us 16т28ц.

Therefore, the final result is 16т28ц.
