<u>Ratios</u>
Let's call
Z=gr of zinc
C=gr of copper
We know the ratio between them in a certain chemical is:
The jar of the chemical contains C=663 gr of copper. Calculate the grams of zinc by solving the above relation for Z:
Multiplying by C:
Substituting the value of C:
Z=156 gr
The jar contains 156 grams of zinc
