Answer:256,384,640
Step-by-step explanation:
Take the ration sum 2x+3x+5x=1280
When we add we get 10x=1280
Then find x by. x=1280/10=128
Then substitute this x value to the ratios 2x=2*128 =256
3x=3*128=384
5x=5*128=640
O.O !!!! That is a lot of formulas! I would help you, but I am in middle school. Sorry
