    Answer: 135 grams of Zinc

    Step-by-step explanation:

    The ratio of Zinc to Copper in this scenario is 3:13 and in this jar there is 585 of Copper.

    Using direct proportion, the grams of Zinc in the jar is:

    3        :           13

    x        :           585

    Cross -multiplying will give:

    1,755 = 13x

    x = 1,755/13

    x = 135 grams of Zinc
