Answer:

zinc = 152 grams

Step-by-step explanation:

Ratio of zinc to copper = 4 : 15

Copper = 570 grams

zinc = x grams

Find x

Ratio of zinc to copper = x : 570

Equate both ratios

4 : 15 = x : 570

4/15 = x/570

Cross product

4 * 570 = 15 * x

2,280 = 15x

x = 2,280/15

= 152

x = 152 grams

zinc = 152 grams
