✔ 最佳答案
a=3ba/b = 3/1
a : b = 3 : 1 = 15 : 5
b=5c
b/c = 5/1
b : c = 5 : 1
a : b : c = 15 : 5 : 1 //

15:5:1
2007-03-11 8:45 pm
a = 3b
a/b = 3
a:b = 3:1
b=5c
b/c = 5
b:c = 5:1
a:b = 3:1 = 15:5
b:c = 5:1
Therefore, a:b:c = 15:5:1
a/b = 3
a:b = 3:1
b=5c
b/c = 5
b:c = 5:1
a:b = 3:1 = 15:5
b:c = 5:1
Therefore, a:b:c = 15:5:1
