Gold that is 24-karat (24K) gold is pure gold. Gold that is 18 parts gold plus 6 parts other metals is 18-karat (18K) gold. To find the percentage of gold in 18K gold, divide the number of parts gold (18) by the total number of parts metal (24) and multiply by 100%. So, 18/24 0.75, and 0.75 100% 75%. Thus, 18K gold is 75% gold. Find the percent­ age of gold in 10K gold and 14K gold.
