✔ 最佳答案
當做 ratio 數時, 最好轉成分數做a:b=1/2:3/4 ==> a/b = (1/2) / (3/4) ==> a/b = 2/3 ==> a:b = 2:3
b:c=1/4:3/8 ==> b/c = (1/4) / (3/8) ==> b/c = 2/3 ==> b:c = 2:3
a:b = 2:3
b:c = 2:3
a:b:c = 4:6:9

a:b=1/2:3/4 , b:c=1/4:3/8
> a:b = 1/2 : 3/4
b:c = 1/4 : 3/8
= 3*1/4 : 3*3/8
= 3/4 : 9/8
> a:b = 1/2 : 3/4
b:c = 3/4:9/8
>a:b:c = 1/2 : 3/4 : 9/8
= 8/2 :24/4 : 72/8
= 4 : 6 : 9
