While mining, Keith found a large metal bar that weighed 42 ounces. Keith was also able to determine that the bar had 30 ounces of silver. What percent of the weight of the bar was silver? Round your answer to the nearest tenth if necessary.

Divide the silver present in the bar by the total weight of the bar to find the percentage of silver in the bar.

[tex]30 / 42 = 0.7142[/tex]

Multiply this decimal by 100 for the percentage.

[tex].7142 * 100 = 71.42[/tex]

Rounded to the nearest tenth, 71.4% of the weight of the bar is silver.
