that it is 22kt gold
920 is 92.0% Gold or 22K Gold.
The number "920" on gold jewelry refers to the purity of the gold in parts per thousand. In this case, "920" indicates that the gold is 92% pure, with the remaining 8% made up of other metals or alloys. This level of purity is commonly found in European countries and is a high-quality standard for gold jewelry.
The marking "920" on gold jewelry indicates that the piece is made of 92% pure gold, also known as 22 karat gold. Pure gold is typically too soft for jewelry, so it is often alloyed with other metals to increase its strength and durability. The "920" marking signifies that the gold content is 92% pure, with the remaining 8% made up of other metals.

10 percent of 920 = 92 10% of 920 = 10% * 920 = 10%/100% * 920 = 92
If you mean 9/20 as a decimal then it is 0.45
80% of 920 = 80% * 920 = 0.8 * 920 = 736
