| **The alloy consists of copper and zinc, the weight of which is 3: 2, the weight of the alloy is 2.5 kg. How much copper is in the alloy and how much zinc.**

1. Let’s find how many parts are in the alloy, if the ratio of the masses of copper and zinc is 3: 2.

3 + 2 = 5.

2. Since the mass of the alloy is 2.5 kg, we find the weight of one of 5 parts:

2.5 / 5 = 0.5 kg.

3. Find the mass of copper and zinc in the alloy by multiplying the mass of one part by the corresponding number of parts:

Copper = 3 * 0.5 = 1.5 kg.

Zinc = 0.5 * 2 = 1 kg.

Answer: the mass of copper in the alloy is 1.5 kg, and the mass of zinc is 1 kg.
