Question

In a certain​ chemical, the ratio of zinc to copper is 3 to 16 A jar of the chemical contains 528 grams of copper. How many grams of zinc does it​ contain?

Answer 1

99 grams of zinc

Explanation:

Ser up a proportion

`(zinc)/(copper)` =
`(zinc)/(copper)` Put in the ration and the actual amount of copper i and solve for the actual number of zinc

`(3)/(16)` =
`(z)/(528)` cross multiply to solve for z

16z = 3(528)

16z = 1584 Divide both sides of the equation by 16

z = 99
