Which karat designation represents a 50% gold alloy?

Explanation:
Karat indicates how much gold is in an alloy, out of a total of 24 parts. Pure gold is 24 karat, so a 50% gold content means 12 of those 24 parts are gold. That makes the designation twelve karat. For context, ten karat is 10/24 ≈ 41.7% gold, fourteen karat is 14/24 ≈ 58.3% gold, and eighteen karat is 18/24 = 75% gold. So the 50% gold alloy corresponds to twelve karat.
