Answer 1

7.6 ounces of silver

Answer 2

Answer: 7.560 ounces

Step-by-step explanation:

Given : The weight of a metal bar = 8.15 ounces

Also, it is given that : 93% of the bar is silver.

We can write 93% as 0.93  [To convert percent into decimal or fraction , we divide it by 100.]

Now, the amount of silver in the metal bar = 93% of 5.15 ounces

Replace 'of' by '×' and '93%' by '0.93' , we get

The amount of silver in the metal bar = $0.93\times8.15\text{ ounces}$

$7.5795\approx7.560\text{ ounces}$

Hence, there are 7.560 ounces of silver in the metal bar.
