Question

In a certain chemical, the ratio of zinc to copper is 3 to 14. A jar of the chemical contains 544 grams of copper. How many grams of zinc does it contain?

Answer 1

`(816)/(7)\ g`

Explanation:

Let

x -----> the grams of zinc

y -----> the grams of copper

we know that

`(x)/(y)=(3)/(14)` -----> equation A

we have

`y=544\ g`

substitute the value of y in the equation A

`(x)/(544)=(3)/(14)`

solve for x

`x=(3)/(14)(544)`

`x=(1,632)/(14)\ g`

simplify

`x=(816)/(7)\ g`
