A factory uses 15 pounds of steel for every 18 pounds of copper. How much copper will the factory 2,700 pounds of steel. (My mom says that the answer is 3,240 pounds. I think she is wrong so I said the answer was 2,250. Please tell me if I'm right!). PLEASE HELP! :D

Basically divide 2700 by 15 = 180
