GIVEN x/3 = y/2 = z/5，xyz<>0，please find the value of the following:
Sol
x/3 = y/2 = z/5=t
x=3t，y=2t，z=5t
a) (x+y)/ z = ?
(x+y)/z
=(3t+2t)/(5t)
=1
b) (x+y+z)/y = ?
(x+y+z)/y
=(3t+2t+5t)/2t
=5
Sol
x/3 = y/2 = z/5=t
x=3t，y=2t，z=5t
a) (x+y)/ z = ?
(x+y)/z
=(3t+2t)/(5t)
=1
b) (x+y+z)/y = ?
(x+y+z)/y
=(3t+2t+5t)/2t
=5
