How many carats does gold jewelry containing 75% gold have?

Gold purity in jewelry is measured in carats, with pure gold being defined as 24 carats. To determine the carat value of gold that contains 75% gold, you can use the formula:

Carats = (Percentage of Gold / 100) × 24.

In this case, 75% of gold would translate to:

Carats = (75 / 100) × 24 = 18.

This means that jewelry containing 75% gold is classified as 18 carats. This classification reflects the proportion of gold in the alloy, providing a standard for quality and value. The higher the carat number, the more gold is present in the jewelry, thus influencing its worth and desirability.
