Calculating the Cost of Purchasing Chocolate Candy

To calculate the cost of purchasing 300 grams of chocolate candy priced at 120 rubles per kilogram, we can follow these steps:

1. Convert the price per kilogram to the price per gram: - Price per gram = Price per kilogram / 1000 - In this case, the price per gram would be 120 rubles / 1000 = 0.12 rubles per gram.

2. Multiply the price per gram by the weight of the candy: - Total cost = Price per gram * Weight of candy - In this case, the total cost would be 0.12 rubles per gram * 300 grams = 36 rubles.

Therefore, the purchase of 300 grams of chocolate candy at a price of 120 rubles per kilogram would cost 36 rubles.
