Question

In a certain chemical, theratio of zinc to copper is 3 to 14. Ajar of the chemical contains 616 grams of copper. How many grams of zinc does it contain?

Answer 1

The jar contains 132 grams of zinc.

Step-by-step explanation:

To determine the grams of zinc in the jar of the chemical, we can set up a proportion based on the given ratio. The ratio of zinc to copper is 3 to 14. Since we know the amount of copper is 616 grams, we can set up the proportion as follows:

3/14 = x/616

Next, we cross multiply and solve for x. Multiply 3 by 616 and divide by 14:

x = (3/14) * 616 = 132 grams

Therefore, the jar contains 132 grams of zinc.
