math question,60y% or 60%y

60%y means 0.6y,or 60/100 times y
60y% means 0.6(y/100)= 0.006y

如果寫60%y做60y% ，會將個數值縮細左100倍~

% = 1/100

60y% = (60y)% = 0.6(0.0y) = (0.6y)
60%y = (60)%y = (0.6)y

if y = 100,
(0.6y) = 1.6
(0.6)y = 60

big difference!

something wrong......
60y% = (60y)% = 0.6(0.0y) = (0.001)(6y) (people see it)
= 60 x y% = 60% x y = (0.6)y = 60%y (in calculator or base on %=1/100)


so you should better to ask your teacher again or just listen your teacher.

60%y 係代表60%＊y,即60/100

60y% and 60%y have 不同的meaning,不能說which is right.
