A US nickel contains 3 ounces of copper for every ounce of nickel. How much nickel is required for 14 pounds of copper.
Let's set up a proportion and cross multiply. Solve for x.
3/1 = 14/x
To find out how much nickel is required for 14 pounds of copper, we need to determine the ratio of copper to nickel in a US nickel.
Given that a US nickel contains 3 ounces of copper for every ounce of nickel, we can express this as a fraction: 3/1 (copper to nickel).
Now, we'll set up a proportion to find the amount of nickel required for 14 pounds of copper:
3/1 = 14/x
In this proportion, the left side represents the ratio of copper to nickel, and the right side represents the amount of copper (14 pounds) to the unknown amount of nickel (x).
To solve for x, we can cross-multiply:
3x = 1 * 14
3x = 14
x = 14/3
Therefore, for 14 pounds of copper, approximately 4.67 ounces of nickel are required.
