Answer 2

Calculating Copper Content in Ore

To calculate the amount of copper in 260 tons of ore containing 8% copper, we can use the following formula:

Amount of copper = (Percentage of copper / 100) * Total weight of ore

Substituting the given values: Amount of copper = (8 / 100) * 260

Calculation

``` Amount of copper = (8 / 100) * 260 = 0.08 * 260 = 20.8 tons ```

So, there are 20.8 tons of copper in 260 tons of ore containing 8% copper.
