Pure gold is quite soft. To make it more useful for such items as rings and jewelry, jewelers mix it with other metals, such as copper and zine. Pure gold is marked 24k (24 karat).
What fraction of a ring is pure gold if it is marked 14k?
If a ring is marked 14k, it means that it contains 14 parts of pure gold out of 24 parts.
Therefore, the fraction of the ring that is pure gold is 14/24 or 7/12.
