✔ 最佳答案
w/x = 6/11, w = 6x/11w/y = 9/16, w = 9y/16
So 6x/11 = 9y/16
x/y = 11*9/16*6
x/y = 99/96
x/y = 33/32

x/y = (w/y)/(w/x) = (9/16)/(6/11) = 99/96 = 33/32

X/y=x/w*w/y=11/6*9/16=99/96
=1 1/32
=1 1/32

w/x = 6/11
y/z = 16/23
w/y = 9/16
x/y = (w/y)/(w/x) = (9/16)/(6/11) = 99/96 = 33/32
y/z = 16/23
w/y = 9/16
x/y = (w/y)/(w/x) = (9/16)/(6/11) = 99/96 = 33/32

33/32
there's no need to know that y/z=16/23 !!!
there's no need to know that y/z=16/23 !!!
