Question 822468
The amount of copper in zinc is one fourth of the total weight. if a sample contains 5 and one third ounces of copper, what is the total weight of the sample?
----
Let the total weight be "x".
------
Equation:
(1/4)x = 5 1/3 ounces
-----
(1/4)x = 16/3 ounces
x = (4/3)16
x = 64/3 = 21 1/3 ounces
