Question

The purity of gold is measured in carats, or 24ths. 18 carats means 18/24 of pure gold. what is the percent of pure gold is in a chain that is 12 karats

Answer 1

Finall Answer:

The chain that is 12 karats contains 50% pure gold.

Step-by-step explanation:

Gold purity is measured in carats, with 24 carats denoting pure gold. For instance, 18 carats means 18/24 parts of pure gold. To determine the percentage of pure gold in a 12-karat chain, divide the karats by 24 (since 24 represents pure gold) and multiply the result by 100 to get the percentage. In this case, 12 karats is equivalent to 12/24, which simplifies to 0.5 or 50% pure gold content in the chain.

Gold jewelry is commonly alloyed with other metals to enhance durability, as pure gold can be relatively soft for certain applications. The karat system provides a simple way to denote the proportion of pure gold in an alloy. Therefore, a 12-karat gold chain contains half its weight in pure gold.

Answer 2

A 12-karat gold chain consists of 50% pure gold, as each karat represents 1/24th of the overall purity.

Step-by-step explanation:

In the realm of gold purity, karats signify the proportion of pure gold in a piece of jewelry on a scale of 24. A 12-karat gold chain translates to
`(_(12)/(24)\)` or
`\(_(1)/(2)\)` pure gold content. The conversion to percentage, calculated by multiplying the fraction by 100, reveals that the chain comprises 50% pure gold. This straightforward relationship between karats and percentage provides consumers with a quick method to assess the gold content in jewelry.

For instance, 18 karats equate to
`\(_(18)/(24)\)` or
`\(_(3)/(4)\)` pure gold, denoting a higher purity level. The simplicity of expressing gold purity as a fraction of 24 allows for easy comprehension and comparison of jewelry compositions.

Thus, understanding the karat system is instrumental for informed decisions, empowering consumers to discern the quality and value of gold jewelry based on its karat rating. In essence, the 50% pure gold in a 12-karat chain exemplifies how the karat scale serves as a practical metric for gauging the purity of gold in various jewelry pieces.
