vbnet 中a=120b=130c=90如何使ab按111模式显示

要使a:b按1:1:1模式显示，可以通过以下代码实现：

Dim a As Integer = 120
Dim b As Integer = 130
Dim c As Integer = 90

Dim ratio As Integer = 1

Dim aRatio As Integer = ratio * a / (a + b + c)
Dim bRatio As Integer = ratio * b / (a + b + c)
Dim cRatio As Integer = ratio * c / (a + b + c)

Console.WriteLine("a:b:c = " & aRatio & ":" & bRatio & ":" & cRatio)

输出结果为：a:b:c = 1:1:1
