To solve this problem, we need to find out how many pounds of pure metal can be obtained from 79 pounds of metal ore, given that the metal ore contains 22.5% pure metal.
Step 1: Convert the given percentage to a decimal.
To convert a percentage to a decimal, divide it by 100. So, 22.5% is equivalent to 0.225 (22.5 รท 100 = 0.225).
Step 2: Calculate the amount of pure metal in the metal ore.
Multiply the weight of the metal ore by the decimal equivalent of the percentage of pure metal:
79 pounds ร 0.225 = 17.775 pounds.
Therefore, from 79 pounds of metal ore containing 22.5% pure metal, you can obtain approximately 17.775 pounds of pure metal.
