From x<0.6y, => 0.6x<0.36y, which compares to w<0.6x, we have
w<0.36y, and we know z<0.54y. So,
3*w<0.36*3y, and 2*z<0.54*2y, we got
3w<1.08y, (1)
2z<1.08y, (2), so (1) divided by (2), we got
[(3w)/(2z)]<1, => 3w<2z, and
w<(2/3)z , Z比W大百分制66.67

Hi man, I think from (1), (2) we can not get 3w/2w <1, am i right?
I think we can not get answer for this question. pls discuss...
