The total amount of silver produced in the world in 2015 was 886.7 million ounces. What percent was produced by the United States?

United States had 35.4 million ounces.

To get the percentage of the silver that US produced, we divide the amount that US produced by the total amount and multiply the quotient by 100%. Mathematically,

= (35.4 million ounces / 886.7 million ounces) x 100%

= 3.99%

So, US produced approximately 3.99% of silver in 2015.
