Calculation of the Cost of 1 kg of Pastila

To calculate the cost of 1 kg of pastila, we can use the information provided. It states that 2/3 kg of pastila was purchased for 28 rubles. We need to find the cost of 1 kg.

Let's break down the information given: - 2/3 kg of pastila = 28 rubles

To find the cost of 1 kg, we can set up a proportion:

(2/3 kg) / (28 rubles) = (1 kg) / (x rubles)

Cross-multiplying, we get:

(2/3 kg) * (x rubles) = (1 kg) * (28 rubles)

Simplifying, we have:

(2/3) * x = 28

To solve for x, we can multiply both sides of the equation by 3/2:

(2/3) * (3/2) * x = 28 * (3/2)

Simplifying further:

x = (28 * 3) / 2

Calculating the value:

x = 42 rubles

Therefore, the cost of 1 kg of pastila is 42 rubles.
