The alloy weighing 360g consists of copper and zinc. The ratio of copper mass to zinc mass is 3: 2. Find the mass of copper, the mass of zinc in the alloy.
1) 3 + 2 = 5 (parts) – is an alloy of copper with zinc;
2) 360/5 = 72 (g) – the mass of one part of the alloy;
3) 72 * 3 = 216 (g) – the mass of copper in the alloy;
4) 72 * 2 = 144 (g) is the mass of zinc in the alloy.
Answer: 216 g of copper, 144 g of zinc.
From the ratio of the mass of copper to the mass of zinc, you can find the number of alloy parts consisting of copper and zinc.
