Copper is 0.2 alloy, zinc is 0.46 alloy, the rest of the alloy is other metals.

Copper is 0.2 alloy, zinc is 0.46 alloy, the rest of the alloy is other metals. what is the mass of the alloy if the mass of other metals is 153?

1. Let’s find the common part of copper and zinc in the alloy, knowing that copper is 0.2 alloy, and zinc is 0.46 alloy.
0.2 + 0.46 = 0.66.
2. Let’s find out what part of the alloy are other metals.
1 – 0.66 = 0.34.
3. Find the mass of the alloy, knowing that the mass of other metals is 153g.
153: 0.34 = 450g.
Answer: the mass of the alloy is 450g.
