已知1/5x:1/6y:1/7z=5:6:7已知(1/5)x:(1/6)y:(1/7)z=5:6:7,求x:y:z

已知1/5x:1/6y:1/7z=5:6:7已知(1/5)x:(1/6)y:(1/7)z=5:6:7,求x:y:z
已知1/5x:1/6y:1/7z=5:6:7
已知(1/5)x:(1/6)y:(1/7)z=5:6:7,求x:y:z

已知1/5x:1/6y:1/7z=5:6:7已知(1/5)x:(1/6)y:(1/7)z=5:6:7,求x:y:z
解由(1/5)x:(1/6)y:(1/7)z=5:6:7
设(1/5)x=5k,(1/6)y=6k,(1/7)z=7k
则x=25k,y=36k,z=49k
则x:y:z=25k:36k:49k=25:36:49
