Answer:

69 grams

Step-by-step explanation:

In a certain​ chemical, the ratio of zinc to copper is 3 to 13. A jar of the chemical contains 299 grams of copper. How many grams of zinc does it​ contain?

From the question, we know:

Zinc : Copper

3 : 13

We are told that : A jar of the chemical contains 299 grams of copper.

The grams of zinc it contains is:

3/13 = x/299

Cross Multiply

13 x = 3 × 299

x = 3 × 299/13

x = 897/13

x = 69 grams

It contained 69 grams of zinc
