Ratio
Zinc : copper
3 : 13

Copper =546 g
Since you’ve got the grams of copper and the ratio you divide them together so that you get one part of copper

546/13=42

Now you do 42x3=126 which is the zinc

The answer is 126 grams of zinc because 546/13 is 42 and 42x3 is 126 giving you the answer 126 grams
