Answer 2

1. 8 * 3 + 6 * 2 = 24 + 12 = 36

The expression represents the total cost of 3 packets of milk priced at 8 rubles each and 2 packs of cookies priced at 6 rubles each. The result is 36 rubles, which is the total amount spent on these items.

2. 6 * 2 + 3 * 2 = 12 + 6 = 18

The expression represents the total cost of 2 packs of cookies priced at 6 rubles each and 2 lemons priced at 3 rubles each. The result is 18 rubles, which is the total amount spent on these items.

3. 8 * 3 - 6 * 2 = 24 - 12 = 12

The expression represents the difference between the total cost of 3 packets of milk priced at 8 rubles each and 2 packs of cookies priced at 6 rubles each. The result is 12 rubles, which is the difference between the amounts spent on these items.

4. (8 * 3) : (3 * 2) = 24 : 6 = 4

The expression represents the division of the total cost of 3 packets of milk priced at 8 rubles each by the total cost of 2 packs of cookies priced at 3 rubles each. The result is 4, which represents the ratio between these amounts.

5. 120 - 8 * 3 = 120 - 24 = 96

The expression represents the remaining amount of money after subtracting the cost of 3 packets of milk priced at 8 rubles each from the initial 120 rubles. The result is 96 rubles, which is the remaining amount of money.

6. 120 - (8 * 3 + 6 * 2) = 120 - (24 + 12) = 120 - 36 = 84

The expression represents the remaining amount of money after subtracting the total cost of 3 packets of milk priced at 8 rubles each and 2 packs of cookies priced at 6 rubles each from the initial 120 rubles. The result is 84 rubles, which is the remaining amount of money.

7. 120 - (8 * 3 + 6 * 2 + 3 * 2) = 120 - (24 + 12 + 6) = 120 - 42 = 78

The expression represents the remaining amount of money after subtracting the total cost of 3 packets of milk priced at 8 rubles each, 2 packs of cookies priced at 6 rubles each, and 2 lemons priced at 3 rubles each from the initial 120 rubles. The result is 78 rubles, which is the remaining amount of money.
