Question 237859: the amount of gold is measured in karats(K), where 24K represents pure gold. the mark 14K on a chain indicates that the ratio between the mass of the gold in the chain and the mass of the chain is 14:24. If a gold ring is marked 18K and it weighs 0.04 oz, what is the value of the gold in the ring if pure gold is valued at $300 per oz?

18:24 is the same as 0.75 or 3/4
-----------------------------
the ring is 3/4 * 0.04 = 0.03 oz. of gold.
---
value of the ring is 0.03*300 = $9
