George has a small coin collection. He has collected 16 gold coins, 28 silver coins, 32 copper coins, and 4 bronze coins. At a flea market, George sells 15% of his coins. Find the number of coins he sold.
First you add up the number of coins in total so: 16+28+32+4 which equals: 80 Then to find 15% you have to do this: 80 divided by 100 then multiply by 15 which is 12. The answer is 12.
