Question

In a certain​ chemical, the ratio of zinc to copper is 3 to 11. A jar of the chemical contains 253 of copper. How many grams of zinc does it​ contain?

Answer 1

69(measurement) of Zinc.

Explanation:

First, to find how much copper can fit into 11, we can divide 253 by 11 to get 23. Once you find that, you know that the converted ratio is x to 23. If you multiply 23 by 3, you get 69. This is why 69 would be your final answer.
