Best ResponseYou've already chosen the best response.2sorry brain fart for a second on my part think about this 12/100 is the amout of platinum in the necklace. 18 grams is the amout of material (12/100) * 18 is the amount of platinum in the necklace. so 54/25 is the amount of platinum in the necklace

Best ResponseYou've already chosen the best response.2remember that 54/25 is just like saying 2.16 so there is 2.16 or 54/25 grams of platinum in the necklace
