Answer 3

It seems like you're performing some calculations involving kilograms (кг) with simple mathematical operations like addition, multiplication, and division. Here's a breakdown of the calculations you've provided:

1. 7 ⋅ 4 = 28 (кг): Multiplying 7 by 4 equals 28 kilograms.
2. 21 + 28 = 49 (кг): Adding 21 kilograms and 28 kilograms equals 49 kilograms.
3. 7 + 14 = 21 (кг): Adding 7 kilograms and 14 kilograms equals 21 kilograms.
4. 21 : 21 = 1 (кг): Dividing 21 kilograms by 21 kilograms equals 1 kilogram.
5. 21 : 7 = 3 (кг): Dividing 21 kilograms by 7 kilograms equals 3 kilograms.
6. 3 ⋅ 4 = 12 (кг): Multiplying 3 kilograms by 4 equals 12 kilograms.

It appears you've correctly performed these calculations involving kilograms. If you have any more questions or need further assistance, please feel free to ask!
